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