BASIN build errors

Hi all,

I've been trying to build BASIN on the CS dept's cluster called Tux.
I've noticed build errors when attempting to compile on this system.
Here are the sys details:

dfj23@tux64-02 ~/basin/basin_kernel $ uname -a
Linux tux64-02 2.6.16-gentoo-nfs-perfctr-r9 #1 SMP Wed Jun 28
14:15:20 EDT 2006 x86_64 AMD Opteron(tm) Processor 244 GNU/Linux

dfj23@tux64-02 ~/basin/basin_kernel $ gcc --version
gcc (GCC) 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)

A log of the error I received is attached. It seems that implicit
casts from ints to MPI_Aints are failing under this version of GCC. I
tried to fix one of the errors with a static cast and it seems to
have cured the problem. These errors seem to be prevalent throughout
the code, but if the casting works then the fix should be easy.
