>Description:

	It would appear as if there's an options parsing bug in CC.

	Attempts to set a manifest constant using the '-D' option fail
	if the option begins with a digit, but in the most obtuse way.

>How-To-Repeat:

	by observation:

	23:08 [852] $ cc -D44bsd hello.c
	hello.c:0: malformed option `-D 44bsd'

>Fix:

	Since it's illegal for a preprocessor macro to start with a
	digit the CC option parser should detect this an report it with
	a meaningful error message.
