Hi Ian,
Thanks a lot for the useful suggestion.

Hi.
Thank you for the modified patch.
I have applied the patch to gcc-4.5 sources and checking the regression

I will run some more tests on the modified (patched) toolchain.
I will share the test results after the regression and other tests are
complete.
