* sysdeps/unix/sysv/linux/speed.c: Add new speed value 460800. Thu May 23 23:09:33 1996 Ulrich Drepper <drepper@cygnus.com> * FAQ: Add answer for 100% source code compatibility to Linux libc by David Mosberger-Tang. Update from bind-4.3.4-T3B. * inet/arpa/inet.h: Add prototypes for inet_pton, inet_ntop, inet_nsap_addr, and inet_nsap_ntoa. * resolv/gethnamaddr.c: Correct compatibility problems (sprintf), remove fourth argument to inet_pton and correct handling of host_addr passing. * resolv/inet_ntop.c: Correct compatibility problems (sprintf). * resolv/inet_pton.c: Remove fourth argument. * resolv/resolv.h: Remove prototypes for inet_nsap_addr and inet_nsap_ntoa. Now on <arpa/inet.h>. * stdlib/gmp-impl.h: Add prototypes for internal functions. Thu May 23 22:49:15 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * Rules (subdir_install): Remove dep on sor-$(subdir). (static-only-routines): Removed variable and associated rules. * sysdeps/unix/sysv/linux/alpha/Makefile (headers): Add sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/ffs.S, sysdeps/unix/sysv/linux/alpha/sigsuspend.S, sysdeps/unix/sysv/linux/alpha/start.S,
