mpi not working

[li pan]

I did try to download and install petsc2.3.2, but end
up with error: mpich can not be download & installed,
please install mpich for windows manually.
In the homepage of mpich2, I didn't choose the version
for windows but the source code version. And compiled
it by myself. Then, I gave the --with-mpi-dir="install
dir". Petsc was configured, and now it's doing "make".
One interesting thing is, I installed petsc in linux
before. The mpi libraries were very large
(libmpich.a==60 mb). But this time in cygwin it was
only several mbs.
