[mpich-discuss] mpich compilation issue

[William Gropp]

You can use gfortran for F77 and F90.  If your requirement is to use  
gfortran for F77 and a different fortran for F90, then they will need  
to use consistent linker names, calling conventions, data sizes, and  
libraries.  The config.log file will have details on why configure  
decided that the Fortran 77 and Fortran 90 compilers were not  
compatible.
