The patch is about using OPTION_SET_P instead of a default
option value set in common.opt.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
gcc/ChangeLog:
* common.opt: Remove Init(2) for some options.
* toplev.c (process_options): Do not use AUTODETECT_VALUE, but
use rather OPTION_SET_P.
