Please test on + something exotic. + + * validate.h + (SCM_NUM2{SIZE,PTRDIFF,SHORT,USHORT,BITS,UBITS,INT,UINT}[_DEF]): + new macros. + + * unif.h: type renaming: + scm_array -> scm_array_t +

i, n: int -> scm_bits_t.x + + * load.c: change int -> size_t in various places (where the + variable is used to store a string length). + (search-path): call scm_done_free, not scm_done_malloc. + + *

surprises if/when the various deeply magic tag + bits move somewhere else. + + * eval.c: changed the locals used to store results of SCM_IFRAME, + scm_ilength and such to be of type scm_bits_t (and not int/long). + (iqq): depth, edepth: int -> scm_bits_t + (scm_eval_stack): int -> scm_bits_t + (SCM_CEVAL): various vars are not scm_bits_t instead of int. + (check_map_args, scm_map, scm_for_each):

(scm_port_t.line_number): int -> long. + (scm_port_t.putback_buf_size): int -> size_t. + + * __scm.h (long_long, ulong_long): deprecated (they pollute the + global namespace and have little value besides that). + (SCM_BITS_LENGTH): new, is the bit size of scm_bits_t (i.e. of an + SCM handle). + (ifdef spaghetti): include sys/types.h and sys/stdtypes.h, if they + exist (for size_t & ptrdiff_t) + (scm_sizet): deprecated. + + * Makefile.am (noinst_HEADERS): add num2integral.i.c + 2001-05-23 Marius Vollmer <mvo@zagadka.ping.de> * snarf.h (SCM_CONST_LONG): Use SCM_VCELL_INIT instead of |
