+ * gcc.c (combine_flag): New global variable, for new driver option.
+ (struct compiler): Add two new fields, to be used when
+ combining multiple input files in a single pass (IMA).
+ (default_compilers): Add values for the new fields to all
+ compiler entries. Modify the "@c" compiler entry for doing IMA
+ properly with "-save-temps" and the "combine" flag.
+ (option_map): Add new driver option, "--combine", to tell driver
+ to pass multiple input files to compiler at one time.
+ (have_o_argbuf_index): New global variable.
+ (store_arg): Modify to assign value to have_o_argbuf_index.
+ (struct infile): Add three new fields, to help with IMA.
+ (display_help): Add help for new "combine" option.
+ (process_command): Remove local variable have_o; add code to check
+ for new "combine" option; remove assignment to combine_inputs.
+ (do_spec_1): Modify to deal with IMA better.
+ (main): Make variable 'lang_n_infiles' local to entire function
+ rather than to a single block. Use flag combine_flag to
+ determine whether to do IMA or not; Modify loop initializing
+ infiles to deal properly with linker files.
+ Add code for doing preprocessing in presence of
+ IMA with "-save-temps" flag. Modify "main" loop to handle
+ multiple input files, in multiple languages, with or without
+ preprocessing, gracefully.
+ * toplev.c (set_src_pwd): Modify to not complain if attempting to
+ re-set it to same directory it's previously been set to (avoid
+ irritating, meaningless warning messages when doing IMA with
+ save-temps).

+ remove documentation about IMA that is no longer accurate; Add
+ documentation explaining what "-combine" does.
