c-pragma.c: Don't elide entire file if !HANDLE_GENERIC_PRAGMAS.

Browse Source 
* c-pragma.c: Don't elide entire file if !HANDLE_GENERIC_PRAGMAS.
	(init_pragma): Avoid warning if pfile happens to be unused.
	* c-pragma.h: Never define HANDLE_GENERIC_PRAGMAS.  Never
	define init_pragma to nothing.  Always prototype
	init_pragma.  Prototype dispatch_pragma if !USE_CPPLIB.

	* c-lex.c (process_directive): Always call dispatch_pragma.
	Initialize entering_c_header to 0.
