Configuring mpfr resulted in strange errors:

Not sure what's going on there. In the INSTALL file (in the top level
directory of the mpfr source) check the sections headed "Building MPFR with
internal GMP header files", "./configure options", and "In case of problem".
There may be something there that helps.

Did you include -IC:/msys/1.0/local/lib in the command ? That should find
gmp.h.

For linking, I think you can just link directly to the dll with
'-LC:/msys/1.0/local/bin -lgmp-3' (assuming libgmp-3.dll is in
C:/msys/1.0/local/bin).
