llvm dev - Jan 2009 - [LLVMdev] linux build problem

I'm away from my Linux machines, if this hasn't been resolved by tonight
I'll send more details.

THe problem in cplus-dem.c is that CPP is conditionally including code 
that comes when HAVE_STDLIB is not defined, including an alternate 
protptype for malloc() that conflicts with the existing one.  This is just 
what causes the error I sent-- no idea what the root cause is.

Thanks,

John

I have posted a patch that fixes it for me. Waiting for someone to
test it on Darwin.

I do have a concern that this might have regressed the Fortran FE.
Could you (or someone who runs it) test this?
