Hi Russ,

thanks for your comments.  Just for clarification to this patch:

This patch should be made anyway, since the NAG compiler provides access to
iargc and getarg only via the above mentioned module.  I do not know if
there is even a way sanctioned by the (current) Fortran standard to access
these, ignoring non-portable solutions.

(If you browse through the above file, you find also a variant for Cray that
uses the former POSIX.9 API for Fortran77, which is sort of obsoleted,
although it is implemented on several platforms.)

Since it is conceivable that others will follow the "NAG way", which looks
quite clean to me, the above could then be easily extended to the followers.

Regards,
-Harald
