Pretty print inline functions. * sysdeps/i386/i486/string.h (__stpcpy_small): Increment __cp not cp. Patch by HJ Lu <hjl@gnu.ai.mit.edu>. 1997-09-20 16:45 Ulrich Drepper <drepper@cygnus.com> * hesiod/hesiod.c (hesiod_init): Use __secure_getenv to get HES_DOMAIN environment variable. Suggested by Mark Kettenis <kettenis@phys.uva.nl>. * hesiod/README.hesiod: A bit of information about Hesiod and how to use it. Written by Mark Kettenis <kettenis@phys.uva.nl>. 1997-09-20 05:15 Ulrich Drepper <drepper@cygnus.com> * manual/maint.texi: Update requirement list. * io/ftw.h: Don't use parameter names from global namespace in prototypes. * stdlib/strtol.c: If used outside glibc handle broken systems which have character classification functions which are not 8-bit clean gracefully.

Miller <davem@tanya.rutgers.edu> * sysdeps/unix/sysv/linux/sparc/sparc64/bits/types.h: ssize_t is a long long int. 1997-09-19 15:12 H.J.
