Re: m68k bootstrapping broken

The above diffs may suggest that something is wrong with the

A non-trivial side-effect of the new frame generation code
is that, when -fomit-frame-pointer is enabled, there's no
longer a wasted slot where the frame pointer would normally
be saved.

This change could affect buggy user code containing
off-by-one stack overflows.

IIRC, -O2 implies -fomit-frame-pointer on the m68k.  Try
building with '-O2 -fno-omit-frame-pointer' and see what
happens.
