Should GMP 4.1+ and MPFR 2.2+ be needed when we're not building gfortran?

[Doug Gregor]

Hello,

The configure changes on the trunk require GMP 4.1+ and MPFR 2.2+. If  
I understand things correctly, these libraries are only needed for  
gfortran. Would it be possible to disable the checks for GMP and MPFR  
when building with --enable-languages=[something not including  
fortran] ?

Please CC me on any replies; I'm not on the main GCC list.

        Cheers,
        Doug
