[MPICH] build mpich2 with Myrinet GM

[Wei-keng Liao]

I got a different error when I built mpich with gcc 3.2.2 at compiling 
file nemesis/src/mpid_nem_alloc.c. (I used ifort for FC environment 
variable.)

In file included from ../include/mpid_nem_impl.h:13,
                 from mpid_nem_alloc.c:7:
../include/mpid_nem_atomics.h: In function `MPID_NEM_SWAP':
../include/mpid_nem_atomics.h:27: warning: dereferencing `void *' pointer
../include/mpid_nem_atomics.h: In function `MPID_NEM_CAS':
../include/mpid_nem_atomics.h:54: warning: dereferencing `void *' pointer
../include/mpid_nem_atomics.h: In function `MPID_NEM_FETCH_AND_INC':
../include/mpid_nem_atomics.h:164: parse error before string constant

Also, I tried Intel icc 8.1.037 and it failed with the message as icc 
9.0.032 and 9.1.046.
