-DTARGET_AIX which is defined in the sp4* optfiles should have already been 
taking care of this.

Your optfile differs from the sp4+mpi in that it uses the 32-bit compilers and 
libraries (as sp4 does). I'm still unclear what really changed but since 
you've got things working its irrelevant.

The includes line:
INCLUDES=-I/usr/lpp/ppe.poe/include/thread
or
INCLUDES=-I/usr/lpp/ppe.poe/include/thread64

specifies the correct MPI library when one uses the _r version of the -32 or 
-64 bit compilers respectively. It's also the higher performing library (as 
opposed to the signals based one in /usr/lpp/ppe.poe/include
