libcpp: * Makefile.am: Add makedepend. * Makefile.in, aclocal.m4: Regenerate. * charset.c: Insert a space to avoid a warning. * directives.c: Include mkdeps.h. (_cpp_handle_directive): Reenable macro expander if appropriate. (undefine_macros): Inline body of _cpp_free_definition for speed. Do not call undef callback or _cpp_warn_if_unused_macro. (cpp_get_deps): New interface. * files.c (search_cache): Add pfile argument. Check for file that would be found by "" or <> search here... (_cpp_find_file): ...not here. Correct recorded start_dir of files found by directory-of-current-file search that would be found by "" or <> search. * init.c (cpp_add_dependency_target): Delete. * internal.h (struct lexer_state): Add discarding_output flag. * lex.c (lex_identifier): Compute hash function while scanning. * macro.c (cpp_scan_nooutput): Disable macro expansion outside directives. * makedepend.c: New file. * mkdeps.c (struct deps): Add vpath vector. (apply_vpath, deps_add_vpath): New function. (deps_free): Free vpath vector. (deps_add_dep, deps_add_target): Use apply_vpath. * symtab.c (calc_hash): Use HT_HASHSTEP and HT_FINISH. (ht_lookup_with_hash): New function. * cpplib.h, mkdeps.h: Update prototypes. * symtab.h: Update prototypes. (HT_HASHSTEP, HT_FINISH): New macros. gcc: * Makefile.in (MKDEPS_H): New shorthand. (c-opts.o): Update dependencies. * c-opts.c: Include mkdeps.h. (handle_deferred_opts): Use cpp_get_deps and deps_add_target, not cpp_add_dependency_target. From-SVN: r82654
