Tue Jul 9 00:14:52 1996 Michael I. Bushnell p/BSG <mib@gnu.ai.mit.edu> * sysdeps/mach/hurd/ioctls.h (MDMBUF, ECHO, TOSTOP, FLUSHO, PENDIN, NOFLSH): Undefine these at start if they are already defined to avoid collision with termbits.h. * sysdeps/generic/termbits.h (ECHO, TOSTOP, NOFLSH): Likewise. (MDMBUF, FLUSHO, PENDIN) [__USE_BSD]: Likewise. Mon Jul 8 13:10:50 1996 Michael I. Bushnell p/BSG <mib@gnu.ai.mit.edu> * sysdeps/mach/hurd/errnos.awk: Skip entries where the error is 0. The "placeholder" entries recently added to errno.texi convert to zero since `???/' is at the front of them. * sysdeps/gnu/errlist.awk (errnoh): Likewise. * sysdeps/stub/setdomain.c (setdomainname): Declare NAME parm __const to conform with unistd.h. * posix/regex.c (re_comp, re_exec): Use weak_function as keyword in function defns instead of weak_symbol (NAME) after the defn. * stdlib/stdlib.h (random): Declare return type to be int32_t.
