Hi Tobias,

As the example in the PR shows, using -fno-protect parens can make a
huge difference. As -fno-protect is in the spirit of -Ofast, enable it
with that option.

Build on x86-64-linux.
OK for the trunk?

OK.

Out of curiosity: Why do you do

gfc_option.flag_protect_parens = optimize_fast ? 0 : 1;

instead of

gfc_option.flag_protect_parens = optimize_fast;

?

Thanks for the patch!

Thomas
