Sat Aug 10 13:17:27 1996 David Mosberger-Tang <davidm@azstarnet.com> * shadow.h: New file. * sysdeps/unix/sysv/linux/netinet/in.h: Move __BEGIN_DECLS/__END_DECLS up so ntohl() et al are bracketed as well. * socket/sys/socket.h [__cplusplus]: Use old-style __SOCKADDR_ARG. g++ 2.7.2 (and earlier) has no transparent unions support. Fri Aug 9 18:50:06 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/sysv/linux/alpha/ioperm.c (_bus_base_sparse): New function to determine the base address of sparse bus memory. (APECS_*): Rename to CIA_*. (APECS_SPARSE_MEM, CIA_SPARSE_MEM): New macros. (platform): Add sparse_bus_memory_base member and initialize. (sparse_bus_memory_base): New variable. Tue Aug 6 10:23:18 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/posix/ttyname_r.c (ttyname_r), sysdeps/posix/ttyname.c (ttyname): Return -1/NULL if !__isatty(fd) (POSIX.1 says so.) * sysdeps/unix/getlogin.c (getlogin): Fix to check fd 0 only. This is not a gross hack, after all---for compatibility, getlogin() really should check fd 0 only and not try to base its operation on the controlling tty. Wed Jul 17 10:54:20 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/unix/getlogin.c (getlogin): Add static variable NAME, change utmp_data from static to auto. Sun Aug 11 02:56:08 1996 Ulrich Drepper <drepper@cygnus.com> * posix/unistd.h [__USE_MISC]: Add prototype for `nice'. Reported by David Mosberger-Tang.
