cpphash.h: #define __extension__ away if GCC_VERSION < 2095 (overly conservative).

Browse Source 
* cpphash.h: #define __extension__ away if GCC_VERSION < 2095
	(overly conservative).  Change extern inline wrappers to
	static inline, define them always, use PARAMS properly.
	* cpplex.c (_cpp_get_directive_token): Don't issue pedantic
	whitespace warnings for \f and \v at the beginning of a line.
