Extended Description

I can compile current CVS llvm using current CVS mainline GCC (3.5.0 20040617).

Compile process terminated with error:

adding std:: prefix to isnan resolve problem in my case

Just to clarify, adding std:: fixes the problem for you? This doesn't seem to
break anything on linux. Brian can you check ppc to see if this allows the
removal of the gross extern C isnan hack?

Oh yeah, btw I checked in this patch:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20040614/015265.html

[llvmbot]

Yes

After this fix and restart gmake lib/Transforms/Utils/Local.cpp compiled
without problems.

[lattner]

Okay, then this bug is fixed. Thanks for the patch!
