cppfiles.c: Read files in, using mmap if possible, then prescan them separately.
* cppfiles.c: Read files in, using mmap if possible, then
prescan them separately.
(read_file, read_with_read): New functions.
* cpplex.c: Don't define UCHAR_MAX.
(_cpp_read_and_prescan): Rename to _cpp_prescan. Don't read
the file here.
* cppinit.c (handle_option): Automatically define __cplusplus,
__OBJC__, __ASEEMBLER__, _LANGUAGE_FORTRAN here when we see
the respective -lang switch.
* cpphash.h (enum node_type, struct hashnode, _cpp_lookup
prototype): Move to...
* cpplib.h: ... here. Rename struct hashnode to struct
cpp_hashnode and give it a typedef. Rename _cpp_lookup to
cpp_lookup. Add 'fe_value' slot, a union tree_node *.
