John and Max,
After I installed the 32 bit cygwin and applied the changes referenced in
Max's email I can now build ecos on my new computer. Thank you both for
your help.

Yes, libmpfr1 is required.

The Cygwin-hosted eCos toolchains were built before 64-bit Cygwin was
available. These toolchains run just fine with a 32-bit Cygwin
installation on 64-bit Windows 7 so, as a workaround, you might attempt
a parallel installation of 32-bit Cygwin (including libmpfr1) on your
new PC. It would be helpful to report back to this list.
In the longer term, we will need to re-build the toolchains against
libraries provided by 64-bit Cygwin.
I hope this helps...
