I’d be in favor or creating a separate package derived from gcc that has
Fortran enabled:
(define-public gfortran
(package (inherit gcc-4.8)
(name "gfortran")
(arguments
;; something that does --enable-languages=fortran
)))
For code that fiddles with --enable-languages, see the definition of
‘gcc-boot0’ in base.scm.
Probably this should be factorized and made available in a nicer way:
(define (gcc #:key (languages '("c" "c++")))
"Return a GCC with the given LANGUAGES..."
(package ...
...))
HTH,
Ludo’.
