[Bug c/14874] New: Compiler driver always returns exit code 0

[martin at mpa-garching dot mpg dot de]

When compiling the following one-liner

#error foo

gcc 3.5 (mainline) returns an exit code of 0,
where earlier versions returned an exit code of 1.

Confirmed, a regression.  Causes libjava to fail to build among others.
Caused by:
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.
