	* sysdeps/unix/sysv/linux/shmat.c: Include sys/shm.h instead of
	sys/sem.h.

	* stdlib/stdlib.h [__USE_SVID]: Declare a64l, l64a.

	* stdlib/l64a.c: Use 6-bit numbers as indices in CONV_TABLE, not
	literal byte values.

	* misc/bsd-compat.c (getpgrp): Define with prototype.

	* misc/init-misc.c (__progname_full): New variable.
	(program_invocation_name, program_invocation_short_name): New aliases.
	(__init_misc): Define with prototype.  Set __progname_full.
	* misc/progname.c: File removed.
	* misc/Makefile (aux): Remove progname.

	* misc/hsearch_r.c (isprime): Define with prototype.

	* sysdeps/unix/sysv/linux/seteuid.c: Just include unix/bsd version.
	* sysdeps/unix/bsd/seteuid.c: Disallow arg of -1.
	* sysdeps/unix/bsd/setegid.c: Likewise.
