Hardcoding values in windows configure script

Description (last modified by balaji)

The windows configure script currently hardcodes values (doesn't perform a compile/run like autoconf to determine values) required for compiling MPICH2. This might be "ok" for some cases but are dangerous for constants like MPI_BSEND_OVERHEAD which depend on the size of internal MPICH2 structures.

We need to find a way (maybe the configure script should just compile and find the values if a compiler is available - is this equivalent to implementing a superset of autoconf using vbscript :) ) to get rid of the problem. This is not a show-stopper but will help us in the long run.

Regards,
Jayesh

We should also investigate whether we can move to compiler wrappers (like the one used by PetSc? - http://petsc.cs.iit.edu/petsc/win32fe ) which will enable us to use autoconf/automake tools for building MPICH2 on windows.
