* 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.
