Thu May 30 03:21:57 1996 Ulrich Drepper <drepper@cygnus.com> * FAQ: Document need of gperf program for developers. * elf/elf.h: Fix typos in comments. * libio/stdio.h [!__STRICT_ANSI__ || _POSIX_SOURCE]: Add prototypes for `ctermid' and `cuserid'. * locale/programs/locale.c: Switch to user selected locale before printing variables. * math/Makefile [$(long-double-fcts)==yes]: Define long-m-routines and long-c-routines. Only if the `long double' data type is available we need to compile the functions. (libm-routines): Add $(long-m-routines). (routines): Remove isinfl, isnanl. Use new file s_isinfl and s_isnanl instead if `long double' is available. * math/math.h: Include <mathcalls.h> again to define `long double' functions. * math/math_private.h: Define data types, prototypes and access macros for `long double'. * stdlib/stdlib.h: Add prototypes for `strtoll' and `strtoull'.
