BTW, I installed the pre-built mpfr and gmp from cygwin setup, but had to get the source version of mpfr in order to get the header files to rebuild gfortran.

Check the return value ($?), I bet it's 53. When you run a binary and
nothing happens, that normally means you're missing a required DLL, in
this case probably mpfr and gmp. You can verify with "cygcheck
/path/to/f951", and then go install those through Cygwin's setup.exe. This is mentioned on the wiki page, BTW.
