cpplib.c: Include symcat.h.
* cpplib.c: Include symcat.h. Add 'origin' field to struct
directive. Add origin values to DIRECTIVE_TABLE. Generate
the strings and function names on the fly. Take the #sccs
entry out of the table if SCCS_DIRECTIVE is not defined.
(_cpp_handle_directive): Decide if the # was at the beginning
of the line here. Issue -pedantic warnings for extended
directives here. Warn about K+R directives with the #
indented, and C89/extended directives with the # not indented,
here.
(do_import, do_include_next, do_warning, do_ident, do_sccs,
do_assert, do_unassert): Don't issue pedantic warning here.
* cpphash.h: Add CPP_WTRADITIONAL macro.
* cpplib.h (struct cpp_options): Rename warn_stringify to
warn_traditional; update comments.
* cppinit.c (handle_option): Set warn_traditional not
warn_stringify.
* cpphash.c: Replace CPP_OPTION (pfile, warn_stringify) with
CPP_WTRADITIONAL (pfile).
* cpplex.c (_cpp_lex_token): Don't decide if directives should
be ignored in -traditional mode here.
* cpplex.c: Copy ISTABLE macros from cppinit.c, and adapt them
to initialize speccase[] and trigraph_map[]. Delete all
references to pfile->input_speccase. Always treat '?' as a
special character. Remove table-initialization code from
_cpp_init_input_buffer.
* cpplib.h (struct cpp_reader): Remove input_speccase field.
* cppinit.c (cpp_cleanup): Don't free input_speccase.
