[LLVMdev] linux build problem

[John Regehr]

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
