* sysdeps/mach/hurd/mmap.c: Fix inverted test of MAP_FIXED. * stdio/vfscanf.c (number): Allow field width to inhibit first digit after base detection. * stdio/vfprintf.c (vfprintf: %s): Never search past the limit specified by the precision. * grp/grpread.c (__grpscan): New function. * grp/grp.h (__grpscan): Declare it. * grp/getgrgid.c: Use __grpscan. * grp/getgrnam.c: Likewise. * pwd/pwdread.c (__pwdscan): New function. * pwd/pwd.h (__pwdscan): Declare it. * pwd/getpwnam.c: Use __pwdscan. * pwd/getpwuid.c: Likewise. Thu Aug 24 16:29:40 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * sysdeps/mach/hurd/mmap.c: Treat (FLAGS & MAP_TYPE) == 0 like MAP_FILE. * hurd/thread-cancel.c: Return EINTR when called on self. * sysdeps/i386/elf/start.S (data_start): Define as weak alias for __data_start.
