Not a problem to redo.. just CPU time and if you don't use it, you lose it. :-D
I am repeating some information so it is all in one post.

In both cases, I built gcc + newlib multilib + rtems multilib to ensure the
entire software base was built with and without the patch.

$ m68k-rtems4.11-gcc --version
m68k-rtems4.11-gcc (GCC) 4.6.1 20110329 (prerelease)

Without patch.. results are at:

With the patch ... results are at:

Only an increase of two passes.  I don't know what was the 3rd test that passed
with the previous patch and not with this one.
