* config/i386/i386.opt: Remove unneeded Init(0) initializations.
(mstackrealign): Do not init to -1.
* config/i386/i386.c (ix86_option_override_internal):
Check opts_set, not opts when setting default value of
opts->x_ix86_force_align_arg_pointer.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.
Committed to mainline SVN.
Uros.
