Thanks for all the responses, but it wasn't clear whether
it is really possible to build MPICH with cygwin. So I
tried the latest nightly and configure failed. Files attached.

As Sangmin said, the patch was pushed to mpich/master. You can download the latest tarball from http://www.mpich.org/static/downloads/nightly/master/mpich/, without need to autogen.

Hi Huiwei,
Please can you let me know when you have corrected the alias fails in a stable version of MPI so I can use that instead of the one in the git repository?  Thanks.
The master file in the repository is too problematic as autogen doesn't want to behave on Cygwin but the stable release should not need autogen so when you have corrected the alias let me know.
Thanks

But need a Windows to run, which we don't have at hand.

Cygwin is basically Linux. The Windows response doesn't apply here.

I am trying to build with cygwin (gcc 4.9.2) on Windows 8.1
See failure at end of m.txt.
Searched for MPIX_Grequest_class_allocate in FAQ and here.

Requested files attached. There is no hwloc/config.log.

The instructions in the README are excellent. That is
appreciated.
