Could you try

gcc -I /c/MPICH2/include/ test.c -L/c/MPICH2/lib/ -lmpi

Since your testprogram depends on the mpi library you need to specify 
the library after your program because the linker goes from left to right.

Did you take a look at mpi.h line 334? On Linux I can see typedef long 
MPI_Aint; . Could you compile with the -E flag to see the preprocessor 
output? Maybe something is overwriting long?
