I recently installed cygwin64 in my windows 8.1 (like 3 days ago) and tried a program that has also worked in Linux and cygwin32, but it didn't work properly. So, I uninstalled the 64 and installed the 32, and it worked flawlessly. I have no idea why, but you could try the 32-bit instead.
BIP!
that is not the way to solve issue!

I am trying to run MPI programs under Cygwin64 version 1.15.1-4 with OpenMPI version 1.7.5-1. The computer is an i7 running Windows 8.0. I do not have any issues compiling programs, but I get the following errors trying to run hello_c.exe (https://github.com/hpc/cce-mpi-openmpi-1.6.4/tree/master/examples):
$ uname -r
1.7.32(0.274/5/3)
cygwin is at 1.7.32 version
the only program at 1.15.1-4 is the X server.
$ cygcheck -cd |grep "1.15"

I have all the packages it said to load (rsh, ssh, all versions of compilers and header files).
I have tried numerous things but always get this error. I would appreciate any help in resolving it.
openmpi 1.7.x on cygwin in general is a bit sensible to strange interfaces.
on my machine I noticed that it can stuck when the wireless is ON,
but no issue on when connect is on LAN.
Can you test openmpi-1.8.2rc4-1 ? You can install it, using
setup-x86_64.exe -X -O -s http://matzeri.altervista.org
It seems a bit less sensible than 1.7.5 to such problems.
Thanks.
