Modified files:
	gcc            : ChangeLog cppfiles.c cpphash.h 

Log message:
	* cppfiles.c (stack_include_file): Only increase the include
	count if we actually process the file properly, as opposed
	to treating it as length zero.  Only call read_include_file
	if not DO_NOT_REREAD.  Handle the -H include file output
	here.
	(read_include_file): Remove now redundant DO_NOT_REREAD check.
	(cpp_included, find_include_file): Simplify pathnames after
	remapping them.  If remapping, don't use the remapped file
	name's buffer as our scratch buffer.
	(cpp_pop_file_buffer): Replace the multiple include macro
	only if it isn't yet set.
	(read_name_map): Simplify remapped names when reading in.
	(remap_filename): Move code to code path that uses it.
	(_cpp_simplify_pathname): Return the input pointer.
	* cpphash.h (_cpp_simplify_pathname): Update prototype.
