I suspect that errno is not a simple integer. Make sure you don't have a declaration like:
extern int errno;
which would trigger the message below.

I think that the Intel compiler automatically includes "errno" in the standard library.

Does anyone know how to link to something that defines errno on gcc/ opteron??
