Yes, people have been pretty helpful in the general case, but this 'package'
:-) may make life easier.  And that's why I asked before attempting it --
someone likely has been there before, let's see what problems and tricks they
found.

When I get to this project (I have to get all the functions I need to compile
under g77 first, and there's ~250,000 lines of quite baroque VAX Fortran
source to go through, and then I need to properly specify the interface in a
way that named COMMON's won't be required, as well as making sure the
functions used don't require passing values back by side effect -- quite a
bit of work before I get to the PostgreSQL side of things), I'll let people
know how it went.
