integers in hex. When we use the printf's %x conversion specifiers for
fixnums, we get incorrect results when the values are negative, because
the argument is actually treated as an unsigned integer.
The end result is that (format t "~x" -1) produces FFFFFFFF
rather than -1. Also, merged together mindless code duplication.

does not have for or exec. We could use CreateProcess and CreatePipe,
et cetera, but it won't buy us anything because the whole point
of this function is to improve the argument passing, and CreateProcess
takes a single command line string, not too different from popen.
* stream.c (pipev_close, make_pipev_stream): Surrounded with
HAVE_FORK_STUFF ifdef.
(pipe_close): Choice of close strategy conditional on HAVE_FORK_STUFF.

that popen accepts a complete command. We need something which
accepts a program name, and a list of arguments, so that
we don't have to assemble together a correctly quoted string.
popen needs an alternative interface resembling execvp.
* eval.c (eval_init): New intrinsic registered, open-pipe-args.
* stream.c (struct stdio_handle): New member, pid.
(stdio_stream_print): Print the pid, if it is nonzero.
(pipevp_close): New close function.

must be closed with pipev_close.

member to zero.

* Makefile (EXTRA_FLAGS): Handy new variable for additional
ad-hoc CFLAGS. Needed by a new test in configure.
* configure: Check for annoying warnings about char being used
as an array subscript when calling the macros from <ctype.h>.
If this occurs, suppress it by #undef-ing the macros.
(lang_flags): Switching fromm _XOPEN_SOURCE to _XOPEN_SOURCE=2
because this is needed on NetBSD to obtain declarations of
popen and pclose.
* stream.c (pipe_close): If we don't have the WIFCONTINUED macro,
then define it to expand to zero. It's absent on NetBSD and they
already seem to have a hack for this because there is a warning about
the function not being defined, but then the program links anyway.
Let's do it properly and not rely on their hack.

(backptr, backptr_idx, partial_gc_count, full): New static variables.
(make_obj): Initialize generation to zero.
(gc): Added logic for deciding between full and partial gc.
(gc_set, gc_mutated): New functions.
* gc.h (gc_set, gc_mutated): Declared.
* hash.c (hash_mark): Changed useless use of vecref_l to vecref.
(gethash_f): Use set when assigning through *found since it
is a possible mutation.
* lib.c (car_l, cdr_l, vecref_l): Got rid of loc macro uses. Using the
value properly is going to be the caller's responsibility.
(push): push may be a mutation, so use set.
(intern): Uset set to mutate a hash entry.
(acons_new_l, aconsq_new_l): Use set when replacing *list.
* lib.h (PTR_BIT): New preprocessor symbol.
(obj_common): New macro for defining common object fields.
type_t is split into two bitfields, half a pointer wide,
allowing for generation to be represented.
(struct any, struct cons, struct string, struct sym, struct package,
struct func, struct vec, struct lazy_cons, struct cobj, struct env,

with no decimal point like 1E1.
* stream.c: (vformat): Keep track of whether or not precision was
given in precision_p local variable.
When printing #<bad-float> pass a precision of 0
to vformat_str, not precision, since precision does not apply.
In ~f and ~e, if the precision was not given, default
it to 3.
Restructured float printing in ~a and ~s. It now just uses sprintf's %g
with a precision. If user does not specify precision, it defaults
to DBL_DIG to print the number with reasonable accuracy.
A .0 is added if it sprintf produces an integer, and the conversion
is ~s rather than ~a.

* parser.l: FLO and FLODOT cases had to be reordered because
the lex trailing context counts as part of the match length,
causing 3.0 to be matched as three characters with 0 as
the trailing context. The cases are split up to eliminate
a flex warning.
* stream.c (vformat): Support bignum in floating point
conversion. Bugfixes: floating point conversion was
accessing obj->fl.n instead of using n.
Changed some if/else ladders to switches.

are now printing floating point numbers into it, letting
the C library handle precision which can generate many digits.
We cap the precision at at 128. New format specifiers ~e
and ~f implemented, which loosely correspond to those of printf.
The ~s and ~a directives handle floats similarly to ~g in
printf, except that they ensure that a decimal point is printed
for the non-exponential notation.

function. This must not flush out more than one character out of this
small buffer, except when we are flushing out the last data.
The correct operation is predicated on the assumption that
a complete character can be pulled out. That's why we move the
buffer to the front after consuming it, and do not automatically
flush until there are four bytes.
(string_out_put_string): We loop the call to string_out_byte_flush
here because when a request comes in to write a Unicode character,
we flush all the bytes, even if the tail of those bytes forms
an incomplete sequence that turns into U+DCxx codes.
(get_string_from_stream): Use the same loop termination test
as in string_out_put_string, for consistency. In that function
it is needed to prevent infinite looping in the case when
the string_out_put_string is being called from string_out_byte_flush
and is thus re-entering it.

is printing other kinds of objects.

* stream.c (format_num): New argument: sign character.
Rewrote to handle precision, width, zero padding and
leading sign similarly to printf.
(vformat): New syntax accepted: a space or + before
the width specifies that a positive sign is to be
explicitly written as a space or + character.
Pass one more argument to vormat_num calls.
Bugfix: go back to vf_init state after processing ~~.

Bignums, based on Michael Fromberger's MPI library, are integrated
into the input syntax, stream output, equality testing, the garbage
collector, and hashing.
The plus operation handles transitions between fixnums and bignums.
Other operations are still fixnum only.
* Makefile (CFLAGS): Add mpi directory to include file search.
(OBJS): Include new arith.o module and all of MPI_OBJS.
(MPI_OBJS, MPI_OBJS_BASE): New variables.
* configure (mpi_version, have_quilt, have_patch): New variables.
Script detects whether patch and quilt are available. Unpacks
mpi library, applies patches. Detects 128 bit integer type.
Records more information in config.h about the sizes of types.
* dep.mk: Updated.
* depend.txr: Make work with paths that have directory components.
* eval.c (eval_init): Rename of nump to fixnump.
* gc.c (finalize, mark_obj): Handle BGNUM case.
* hash.c: (hash_c_str): Changed to return unsigned long
instead of long.
(equal_hash): Handle BGNUM case.
(eql_hash): Handle bignums with equal-hash, but other
objects as eq.
* lib.c (num_s): Variable renamed to fixnum_s.
(bignum_s): New symbol variable.
(code2type): Follow rename of num_s. Handle BGNUM case.
(typeof): Follow rename of num_s.
(eql): Handle bignums using equal, and other types using eq.
(equal): Handle BGNUM case.
(chk_calloc): New function.
(c_num): Wording change in error message: is not a fixnum.
(nump): Renamed to fixnump.
(bignump): New function.
(plus): Function removed, reimplemented in arith.c.
(int_str): Handle integers which are too large for wcstol
using bignum conversion. Base 0 is no longer passed to
wcstol but converted to 10 because the special semantics
for 0 would be inconsistent for bignums.
(obj_init): Follow rename of num_s. Initialize bignum_s.

(string_in_get_line): Following up TODO. Fixed broken
function. Now get_line on a string stream properly returns characters
up to and not including the next newlne character, and also consumes
the newline character. Other cases are handled properly, also:
the stream being at EOF already, or at the last line not being
newline-terminated.

warning.
(eval_init): New functions registered: typeof and vector functions,
as well as length_list.
* lib.c (length): Function renamed to length_list, because it is
list specific.
(length_vec, size_vec, vector_list): New functions.
(length): New function, generic over lists, vectors and strings.
* lib.h (length_list, length_vec, size_vec, vector_list): Declared.
* match.c (h_var, h_fun, robust_length, v_deffilter, v_fun): Use
length_list instead of length.
* parser.l: Introduced # token.
* parser.y (vector): New nonterminal.
(expr): vector is a kind of expr.
(chrlist): Bugfix: single-character syntax was not working;
for instance #\x to denote the charcter x.
(lit_char_helper): Use length_list instead of length.
* stream.c (string_in_get_line): Bugfix: this was using
the wrong length function: length was being applied to a string.
The genericity of length makes that correct now, but changing
to length_str anyway.
* txr.1: Blank sections created for functions. Vector syntax
documented.

the sequencing! Making it an inline function broke the tests.
But we can't have multiple evaluation either, so it's going to use
a temporary lexical variable.
(uses_or2): Macro which declares the lexical variable needed by or2.
* debug.c (debug): add uses_or2.
* eval.c (eval_intrinsic, op_modplace): Likewise.
* lib.c (lazy_str, lazy_str_force_upto, lazy_str_get_trailing_list):
Likewise.
* match.c (h_parallel, v_freeform, v_parallel, v_output): Likewise.
