Today's (2008-02-05; rev. 132112) m68k-rtems*-gcc from gcc-trunk ICEs when
building rtems :

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
This ICE is reproducible for different -m<*> flags and for different source
files. However it only seems to occur when being combined with
-fomit-frame-pointer.
=> Wild guess: m68k's -fomit-frame-pointer handling is broken.
