Configured with

 ../configure --prefix=/pkgs/gcc-test --with-gmp=/pkgs/gmp-4.1.4/
--with-mpfr=/pkgs/gmp-4.1.4/

The following messages come up during configure:

checking for correct version of gmp.h... yes
checking for correct version of mpfr.h... buggy version of MPFR detected
checking for any version of mpfr.h... yes
The following languages will be built: c,c++,fortran,java,objc
*** This configuration is not supported in the following subdirectories:
     target-libmudflap target-libada gnattools
    (Any other directories should still work fine.)

In /pkgs/gmp-4.1.4/include/mpfr.h we find

/* Define MPFR version number */
#define MPFR_VERSION_MAJOR 2
#define MPFR_VERSION_MINOR 1
#define MPFR_VERSION_PATCHLEVEL 1

which is indeed insufficient to build gfortran, but gfortran is still
configured in and "make bootstrap" fails with
