Log message:
	2004-04-05  Caroline Tice  <ctice@apple.com>
	
	* 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).
	* doc/invoke.texi: Add "-combine" to list of Overall Options;
	remove documentation about IMA that is no longer accurate; Add
	documentation explaining what "-combine" does.
	* ada/lang-specs.h: Add initialization values for new fields in
	"struct compiler".
	* cp/lang-specs.h: Likewise.
	* f/lang-specs.h: Likewise.
	* java/lang-specs.h: Likewise.
	* objc/lang-specs.h: Likewise.
	* treelang/lang-specs.h: Likewise.
	
	Fix gcc driver to work properly with IMI.
