Well --download-hypre should work with gnu compilers.

However with MS/Intel compilers - hypre should be installed separately
- and sepcified to PETSc configure [with --with-hypre-include,
--with-hypre-lib optons]. Neither of 3.1/3.2 support --download-hypre.

The hypre tarball should have the relavent instructions for a windows
install. [in the users manual]
