is there a way to find out gfortran version and/or options from a given binary?

[Arjen Markus]

Hm, I ran it without any options - would that be equivalent to -g then? A
rather awkward workaround might be to compile one source file containing
this code with -g, but that is pushing things to the limit.

Regards,

Arjen
