Starting with GCC version 4.6, the default setting (when not optimizing for
size) for 32-bit Linux x86 and 32-bit Darwin x86 targets has been changed to
@option{-fomit-frame-pointer}. The default can be reverted to
@option{-fno-omit-frame-pointer} by configuring GCC with the
@option{--enable-frame-pointer} configure option.
