[patch] ping1 unbreak bootstrap on FreeBSD ppc

[Andreas Tobler <andreast-list@fgznet.ch>]

[-- Attachment #1: Type: text/plain, Size: 1113 bytes --]

All,

I'd like to commit the below patch to gcc trunk and gcc-4.5.

I have an ok from DJE, but I still await a comment from Loren.

This is now pending for more than a month. And I'd like to push this out.

Am I allowed to commit this to 4.6, or do I have to wait for 4.7 and 
then backport to 4.6?

Test results are available on the list and I'll send updated results soon.

Also, what is the commit stage for 4.5? I'd like to apply it there as well.

I'd appreciate any help on this since I get asked offlist about this 
patch. And if possible I'd like to point people at the latest gcc 
snapshot/release instead of unapproved patches.

Thanks,
Andreas
