before using clog(). It's possible for gcc to provide the "complex
double" type, but for the system not to have the complex funcs.
(scm_exp): Ditto HAVE_CEXP for cexp().
tc16 values so big, real, complex and fraction can be distinguished.
(scm_i_tag_name): Return "number" for scm_tc7_number, not NULL. NULL
was making numbers come out as "type 23" in gc-live-object-stats.
Fix tests of the tc16 number types, they were checked under
scm_tc7_number, but the values went down the tag>=255 smob case.
Put smob case under scm_tc7_smob instead of using tag>=255, per
recommendation in comments with scm_tc7_smob to use symbolic values.
Use SCM_TC2SMOBNUM to extract scm_smobs index, instead of explicit
code. Lose some unnecessary "break" statements.
(scm_i_card_statistics): Use scm_hashq_create_handle_x and modify the
element returned, rather than two lookups scm_hashq_ref and
scm_hashq_set_x.
allocating a tail array. If there's no such then those tail fields
are uninitialized and garbage SCMs there can cause a segv if printed
(after fetching with struct-ref).
(scm_i_input_error, scm_lreadr, scm_lreadrecparen): Corrections to
port line number type, should be "long" not "int", as per line_number
field of scm_t_port. (Makes a difference only on 64-bit systems, and
only then for a linenum above 2Gig.)
'total-cells-allocated in gc-stats output. This allows profiling
of a program's memory use.
* gc-segment.c (scm_i_sweep_some_cards): update
scm_gc_cells_allocated_acc when sweeping happens.
* gc.h: add scm_gc_cells_allocated_acc, scm_last_cells_allocated.
F_DUPFD, F_GETFD, F_SETFD, F_GETFL, F_SETFL, F_GETOWN, F_SETOWN, these
are all ints (per command arg to fcntl). Likewise FD_CLOEXEC which is
an int arg to fcntl.
scm_from_long for O_RDONLY, O_WRONLY, O_RDWR, O_CREAT, O_EXCL,
O_NOCTTY, O_TRUNC, O_APPEND, O_NONBLOCK, O_NDELAY, O_SYNC and
O_LARGEFILE. These are all int not long.
and SCM_CRITICAL_SECTION_END, believe not needed. Their placement
meant #\nul in the input (detected by scm_to_locale_string) and a bad
flags arg (detected by scm_to_int) would throw from a critical
section, causing an abort().
