Update.
1998-04-21 21:49 Zack Weinberg <zack@rabi.phys.columbia.edu> * misc/sys/cdefs.h: New macro __REDIRECT to support changing the asm symbol name of functions. * include/features.h: Kill redundant test. * dirent/dirent.h: Use new macros to implement __USE_FILE_OFFSET64. * io/ftw.h: Likewise. * io/sys/stat.h: Likewise. * io/sys/statfs.h: Likewise. * io/sys/statvfs.h: Likewise. * libio/stdio.h: Likewise. * resource/sys/resource.h: Likewise. * rt/aio.h: Likewise. * posix/unistd.h: Use new macros for __USE_FILE_OFFSET64 and __FAVOR_BSD. * signal/signal.h: Use new macros for BSD vs. SysV signal(). * misc/Makefile: Drop bsd-compat.c. Make libbsd-compat.a a dummy library. * misc/bsd-compat.c: Removed.
