You should be able to just put the -O3 or whatever on the end. From the
gcc manual:
"If you use multiple `-O' options, with or without level numbers, the
last such option is the one that is effective."
Also from the gcc manual:
"`-O' also turns on `-fomit-frame-pointer' on machines where doing so
does not interfere with debugging."
So banning -fomit-frame-pointer makes sense, as optimization will
already turn it on if it doesn't break debugging.
