cppexp.c, [...]: Eradicate all traces of code dependent on traditional, lang_chill, or lang_fortran.

	* cppexp.c, cpphash.c, cpphash.h, cppinit.c, cpplex.c,
	cpplib.c, cpplib.h: Eradicate all traces of code dependent on
	traditional, lang_chill, or lang_fortran.

	* cppfiles.c: #undef strcmp to suppress warning about macros
	used without arguments.
	(_cpp_execute_include): Use f, not fname, in "No include path"
	error.
	(_cpp_pop_file_buffer): New function.
	* cpplib.c: Don't include <sys/mman.h>.
	(cpp_push_buffer): Set line_base and lineno in new buffer.
	(cpp_pop_buffer): Use _cpp_pop_file_buffer.

	* cpplex.c: Move all prototypes and structure declarations to the
	top of the file.  Properly parenthesise some macro arguments.
	(cpp_scan_line): New function.
	(special_symbol [case T_INCLUDE_DEPTH]): Use pfile->include_depth,
	don't need to walk up the stack counting.
