>Description:
	gcc-2.95.x: ^M not ignored after #pragma
>How-To-Repeat:
	#pragma prototyped^M
	typedef int __sig_atomic_t;
	typedef __sig_atomic_t sig_atomic_t;
	
	Compile and watch the compiler barf. (Ctrl-M is ASCII 13 (CR) and
	commonly used before ^J (LF) on some "operating systems")
	
	garloff@gum01m:~/Linux $ gcc  -c gdgen5.E.c
	gdgen5.E.c:3: parse error before sig_atomic_t'
	gdgen5.E.c:3: warning: data definition has no type or storage class
	garloff@gum01m:~/Linux $ gcc -v
	Reading specs from /usr/lib/gcc-lib/i486-suse-linux/2.95.3/specs
	gcc version 2.95.3 20010315 (SuSE)
	
	PS: Thx to John Ellson (Lucent) for finding this bug!
>Fix:
	Either the preprocessor should dump all ^M before evaluating
	anything and before passing data to the compiler, or (better) 
	the compiler should ignore the ^M.
	It has been fixed on the 2.96 snapshots that I've seen and 
	it also is fixed in 3.x.
