* 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.

only if it isn't yet set.

include chain.
(_cpp_compare_file_date): Don't choose the search chain here.
