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...
