dnl Platform-dependent/preprocessed sources. This is slightly
dnl subtle: file random.F is a preprocessable file. However,
dnl there are also versions available for VAX/VMS
dnl (random.F__vms) and Microsoft Fortran (random.F__win), and
dnl these are sufficiently distinct that it's not worth just
dnl configuring the function name.
dnl
dnl The random and gresid VMS and Windows files have a .F
dnl extension: there's no preprocessable code in them, but they
dnl have to have the same name as the file which does have.
dnl
dnl Problem: Is the code in the *__win files specific to Windows
dnl or to MSFortran? Since you'd only get MSFortran on Windows, I
dnl suppose it's the former (or might as well be).
dnl
dnl The __vms files will never be matched by this macro (will the
dnl __win files?), since config.guess doesn't cover VMS at all, but
dnl the following, as well as documenting the relationship, also
dnl causes the corresponding files to be included in the
dnl distribution, where they might be of use to someone.
