There were 191 tests which failed to build.  There were 190 lines with 
stor-layout.c:258 on them.  So this error is responsible for almost all 
of the ACATS build failures on bfin.

bfin-rtems4.9-gcc -c -fstack-check -O -gnatws -O2 -I/home/joel/work-gnat/svn/gcc/gcc/testsuite/ada/acats/work-eZKit533/support a87b59a.adb

I tried this at various optimization levels and it doesn't matter.
