	When getting 1.1 up on Sun 3.0, I found that the sources
cross-compiled to C on our VAX and then bootstrapped produced a working
cfront, but this cfront then died when trying to recompile main.c with
the ever popular ``internal error: bus error (or something nasty like that)''.
At first it appeared this was the problem with print.c which Mike Wescott
posted a patch for recently, however, this turned out not to be the
case. cfront was dying in norm::normalize() (in norm.c). After considerable
poking around, I found that simply moving the line

	#include <signal.h>

	from right before the routine 'core_dump' to right after the line

	#include <ctype.h>

	in main.c made this problem go away. Darned if I know why, or 
if anyone else has seen this one, but cfront does recompile itself now 
on our Suns.
