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. + + * Makefile (conftest, conftest.o, conftest.syms): New targets. + Used by the configure script. + + * configure (intptr, nm): New configuration variables. + Generating config.make is no longer the last step; compiler tests are + performed after config.make is set up, so that rules in the Makefile + can be used for doing the compiling. (This is the cleanest way to do + it, since the paths to the tools may contain Make variable expansion + syntax). New steps are added to try to detect whether the compiler has + a wider integer type than the c89 long, and which of the available + types (including, potentially, the extra wide type) is suitable for + holding a pointer. Results are generated into a header config.h. + + * dep.mk: Regenerated. + + * lib.h (NUM_MAX, NUM_MIN): Now derived from INT_PTR_MAX and + INT_PTR_MIN macros, which come from config.h. + (cnum): New typedef name. + (cobj ops, tag, auto_str, static_str, litptr, lit_noex): + Changed long to cnum. + (num, c_num): Declaration updated. + + * lib.c (equal, length, num, c_num, plus, minus, neg, search_str, + cat_str, vector, vec_set_fill, obj_print, obj_pprint): Changed + long to cnum. + + * gc.c (mark_obj): Changed long to cnum. + + * hash.c (stuct hash, ll_hash, hash_mark, hash_grow, + hash_process_weak): Changed long to cnum. + + * match.c (complex_open, do_output_line, do_output, match_files): + Changed long to cnum. + + * parser.h (lineno): Declaration updated. + + * parser.l (lineno): Redefined as cnum. + (grammar): Changed long to cnum. + + * parser.y (%union/yystype): num member changed to cnum. + of config.h added. + + * regex.c (nfa_run, nfa_machine_match_span, search_regex): + Changed long to cnum. + + * regex.h (struct nfa_machine): Members last_accept_pos and count + changed to cnum. + (nfa_run, nfa_machine_match_span): Declarations updated. + + * stream.c (struct fmt): New type. + (fmt_tab): New static array. + (num_fmt): New static pointer. + (detect_format_string): New function. + (vformat): Changed long to cnum. Formatting of numbers uses + num_fmt. + (stream_init): Call detect_format_string. + + * txr.c, unwind.c, utf8.c: include config.h. + + * unwind.h (internal_error): Local declaration of num updated. + 2009-11-21 Kaz Kylheku <kkylheku@gmail.com> Introducing symbol packages.
