...and I missed one test case; need to discard comments in macros while
parsing CPP expressions.

Once again, an updated patch is attached, and here's an updated ChangeLog
entry.

	* cppinit.c (cpp_create_reader): Initialize
	discard_comments_in_macro_exp.
	(COMMAND_LINE_OPTIONS): Add "-CC" option.
	(cpp_handle_option) Handle "-CC" option.
	* cpplib.c (_cpp_handle_directive): If processing
	a `#define' directive and discard_comments_in_macro_exp
