### If we haven't been forced to use a particular Fortran compiler,
### try to find one using any one of several common Un*x Fortran
### compiler names.  Put fc last to avoid confusion with some vendor's
### /bin/sh fc builtin.
###
###    f77 : most Unix systems
###    xlf : IBM / AIX
###   cf77 : Cray / Unicos
###    g77 : GNU Fortran
###     fc : Convex
###
### If a compiler is found, check to see if it is compatible with our
### assumptions.  If it is, use it.  Otherwise, look for f2c.  If we
### can't find a compatible fortran compiler or f2c, issue a warning.
###
### I don't think the Cray compiler will ever work like f2c...
###
### The configure options --with-f77, --with-g77, or --with-f2c
### force f77, g77 or f2c to be used.  It is also possible to use
### these options to specify the name of the compiler.  For example,
### `--with-g77=/opt/gnu/bin/f77' says that we are using g77 but it is
### installed as /opt/gnu/bin/f77.
