When trying to configure 4.3.0 it tells me that I need GMP 4.1+ and MPFR 2.2.1+. Yet under Cygwin the libraries appear as dlls and named as cygmp*.dll and cygmpfr*.dll. How do I get the configure script to recognize them?
The short answer: you probably didn't select the right packages.  You
need to install the -devel packages.

gcc configure is looking for the header files for gmp and mpfr. The .dll's and .a's alone aren't sufficient. Personally, I think it's unnecessarily confusing to have cygwin installation options which don't supply the headers, particularly when configure tests don't simply say "required header file for mpfr missing" or some such. But, if you installed binaries for gcc and gfortran from the gfortran wiki, for example, the .a's and .dll's would be sufficient.
