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.

------- Additional Comments From pinskia at gcc dot gnu dot org 2004-04-07 12:23 -------
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.
