discovered on Red Hat EL 4 with gcc 3.4.3.
In the collect loop, set car(success) to nil.
Somehow the generated code hangs on to the last
matching position for a regex, preventing GC.

on 32 bit x86 Fedora. This happens because the lazy list variable
``data'' in the match_files function is optimized to a register,
but a stale value of that variable persists in the backing storage.

can be converted to a type long and vice versa. The configure
script tries to detect the appropriate type to use. Also,
some run-time checking is performed in the streams module
to detect which conversions specifier strings to use for
printing numbers.

a system package instead of being hacked with the $ prefix.
Keyword symbols are provided. In the matcher, evaluation
is tightened up. Keywords, nil and t are not bindeable, and
errors are thrown if attempts are made to bind them.
Destructuring in dest_bind is strict in the number of items.
String streams are exploited to print bindings to objects
that are not strings or characters. Numerous bugfixes.

we have an unhandled exception too early in initialization.
Use C stream to print an error message and abort.
Using the nil stream variable will just cause a recursion bomb.

False positive return fixed.
(match_line): Fixed merge to use eval_from
rather than direct symbol binding.

we wouldn't have to declare object variables at all, so why
use an obtuse syntax to do so?)

abstraction instead of directly using C standard I/O,
to eliminate most uses of C formatted I/O,
and fix numerous bugs, such variadic argument lists which
lack a terminating ``nao'' sentinel.
Bug 28033 is addressed by this patch, since streams no longer provide
printf-compatible formatting. The native formatter is extended with
some additional capabilities to take over.
The work on literal objects is expanded and they are now used
throughout the code base.
Fixed bad realloc in string output stream: reallocating by number
of wide chars rather than bytes.

use wide character functions so that there is no illicit
mixing. (But the goal is to replace this usage with txr streams).
|

|
|
|
|
|
|
|

This is incomplete. There are too many dependencies on
wide character support from the C stream I/O library,
and implicit use of some encoding which may not be UTF-8.
The regex code does not handle wide characters properly.
Character type is still int in some places, rather than wchar_t.
Test suite passes though.

unboxed. If the lowest bit of the obj_t * pointer is 1, then
the remaining bits are a number. A lot of assumptions are made:
- the long type can be converted to and from a pointer
- two's complement.
- behavior of << and >> operators when the sign bit is involved.

Lazy strings implemented, incompletely.
Changed string function to implicitly strdup; non-strdup
version changed to string_own. Fixed wrong uses of strdup
rather than chk_strdup.
Functions added to regex module to provide regex matching
as a state machine to which characters are fed.

the way match_line treats variables.
