This is an extension thought up by Digital Equipment Corporation when
they still were a major force in Fortran deployment and development
(i.e. 2 decades back).
It's very hard to support in a general sense - there's a nice discussion
going on on comp.lang.fortran on exactly *how hard* it is, including the
people who originally thought this up.
I'm sorry, g77 will never support this (and g95 most probably won't,
either).
I'm sorry.
