Looks reasonable.

Yow.  These and the other pile of errors are complaining about
perfectly reasonable looking system headers.  I don't know why pgcc
thinks "typedef __ssize_t ssize_t" is invalid.  But that's outside
of our control.  Maybe you need to fix your pgcc install so that
it picks up the PGI-specific versions of these headers instead.

The first real errro:

This may be because the PGI compiler does not understand typeof().
It's quite handy, but not part of any C standard.  Can you try
editing line 36 of list.h to change that "#ifdef _CRAYC" to "#if 1"
and see if it builds?  If it does, can you try "#ifdef __PGI", then
do "make clean" and "make" again?

But compiling with anything other than gcc is probably not worth the
effort.  There isn't much of anything that is performance critical
in mpiexec, so using a specialized compiler like PGI won't show any
improvment.
