I noticed today that stdio.h won't compile with gcc -traditional.  The
cause is the use of GCC's __attribute__ extension to define the
special printf calls.  Here is the fix:

diff -c  sys/sys/cdefs.h.mhw1 sys/sys/cdefs.h
*** sys/sys/cdefs.h.mhw1	Sat Dec  4 05:36:48 1993
--- sys/sys/cdefs.h	Sat Dec 11 07:40:52 1993

  #define	const		__const		/* GCC: ANSI C with -traditional */
