Hi

I have a patch that both of you (and anybody else with a problem
building pnetcdf against an MPI-1 implementation) can try out.  It
will disable the nonblocking API, but pnetcdf will use only mpi-1
routines.    (actually, because this patch does not adjust
configure.in, it has the effect of disabling the nonblocking api for
all users).  

If you could try out this patch and let me know how well it works for
you, I'll add it to the next release (with a proper configure check,
of course :> )
