troubling warnings with mpich-gm-1.2.4..8a

I get hordes of the following warnings anytime I compile C++ mpich code
using mpich version 1.2.4:

/usr/local/mpich-gm-1.2.4..8a/include/mpi2c++/functions_inln.h: In
function `void PMPI::Pcontrol (int, 
...)':
/usr/local/mpich-gm-1.2.4..8a/include/mpi2c++/functions_inln.h:145:
warning: cannot pass objects of 
non-POD type `struct va_list' through `...'


Even the simplest mpi program yields this warning.  Does anyome know
what this means/how to fix it/how to make it go away?
