* introduce the mbstate_t typedef.
impacts gnu libiconv, which has already been taken care of.
* Prepare for mb stuff to really exist, replace macro MB_CUR_MAX with
an external variable __mb_cur_max (impacts libX11 and various ports).
* use mbstate in all the mb <-> wchar functions with state.
* add a stub iswctype function allowing some ports to compile.
bash and gdiff are missing wcscoll, and need to be told there's no i18n
until this is fixed.
Discussed and matthieu, otto, millert, kettenis, deraadt.
Major libc bump
getopt_long_only(). At some point this should replace the BSD
getopt(3) but we are not there yet.
While I am here add protection from the multiple getopt() definitions
due to conflicting standards.
syntax error if the #define happens before stdlib.h is included.
If abs is #defined, #undef and issue a warning. This is similar
to what Tru64 UNIX does and is effectively the same as what happens
on Solaris (though on Solaris the real abs() is a macro).
Needed for cap_mkdb to really DRT when given several input files or
an output file with a different name from the input file.
cvs: ----------------------------------------------------------------------
__null is a magic constant of integral type that converts to a null pointer
as should be, but warns for ambiguity when used to resolved an overload
between an integral type and a pointer type.
All POSIX libc api now there (to P1003.1c/D10)
(more md stuff is needed for other libc/arch/*)
(setlogin is no longer a special syscall)
Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS).
Doc some re-entrant routines
Add libc_r to intro(3)
dig() uses some libc srcs and an extra -I was needed there.
Add more md stuff to libc_r.
Update includes for the pthreads api
Update libc_r TODO
