c-lang.c (c_post_options): Call cpp_post_options.
* c-lang.c (c_post_options): Call cpp_post_options.
* cppmain.c (main): Similarly.
* fix-header.c (read_scan_file): Similarly.
* cp/decl2.c (cxx_post_options): Similarly.
* objc/objc-act.c (objc_post_options): Similarly.
* cppinit.c (cpp_start_read): Move option consistency checks
to cpp_post_options. Don't call init_dependency_output.
If needed, add default target and main file dependency.
(OPT_MD, OPT_MMD): Remove.
(OPT_MF): New.
(cpp_handle_option): Update for OPT_* changes.
(cpp_post_options): New.
(init_dependency_output): Command line -MF overrides environment
variables. Don't set default target etc. Suppress output
if dependencies are going to stdout.
(print_help): Update.
* cpplib.h (cpp_post_options): New.
* gcc.c (cpp_options): Update for -MD, -MMD, -MF.
