970530: compiling .F files with NAG f90

Dear Steve,

Russ has passed your problem on to me (I'm the creator of the
installation procedure).

The NAG people are correct in that the .F extension is used only by
exotic systems.  Such systems include (but are not limited to) the
following:

    System      Compiler
    ------      --------
    AIX         xlf
    BSD/OS      fort77
    HP-UX       fort77
    IRIX        f77
    IRIX64      f77
    Linux       fort77
    OSF/1       f77
    SunOS 4     f77
    SunOS 5     f77
    UNICOS      f90
    ULTRIX      f77

These are, indeed, highly exotic systems.  ;-)

Tell the NAG people to get off their butts and join the rest of the
world.  :-)

The configure script should have automatically determined that your
FORTRAN compiler doesn't support .F files.  I wonder what when wrong.

Would you please send me the standard output from your configure script
and also the file config.log.
