 I don't write code in Fortran, but some of the ports I use require
 Fortran.

 Different Portfiles depend on different Fortran compilers. Contrast
 fftw-3(g95,  gfortran/gcc4.2, gfortan/gcc4.3) pgplot(g77 on PPC,
 gfortran/gcc4.2 on i386) and cfitsio(gfortran/gcc42). There are at least 4
 compilers to choose from.

 My request: formulate a standard to allow any of the compilers to be
 selected with a variant. The fftw-3 Portfile comes closest with variants
 to select any one of 3 compilers. If possible, I'd like to see g77
 deprecated.
