>Description:
	A too large bitfield is a constraint violation of C99 6.7.2.1p3.
	I think it violates ANSI and K&R too, but I can't check that.
	Gcc only gives a plain warning, even under -std=c99 -pedantic.
>How-To-Repeat:
	bash$ echo 'struct { int i : 9999; } x;' > a.c
	bash$ ./xgcc -B./ -std=c99 -pedantic -o /dev/null -S a.c

	a.c:1: warning: width of `i' exceeds its type
