Thanks, I'm installing this one in my local tree. All testsuite
results I'll post from now on will have this patch installed. I hope
Jeff agrees to have it installed for the release. It would be a pity
to be unable to build gcc 2.95 without -O3, as I've been doing on all
previous releases of gcc and egcs.
