When you say 'Supporting --download-hdf5 in Cygwin' and refer to 64-bit - you
mean MS compilers or cygwin gcc/gfortran?

The error message should come up only with MS compilers.

Presumably --download-hdf5 should work with gnu compilers - if it doesn't - it
probably needs some tweaking.

Wrt repo - we now have a single git repo bitbucket.org/petsc/petsc
where all petsc/buildsystem changes should go to.
