I was thinking that the problem was related to this.  This macro
does exist, and I am pretty sure that the call to pgcc is picking it
up.

However, the problem is that no function in the mvapich distribution
calls this function.  It is coming form some of the OFED libraries.
To me, it appears that I have to build the OFED libraries with
pgcc (not gcc) so that it picks up the macro.  I am highly reluctant
to do this, because it means I need multiple versions of OFED, which
makes no sense.
