I am using gcc5-devel to maintain some inhouse mixed-language (C++ main
& some lower stuff, *LOTTA* ANSI C, bits of FORTRAN77) program. I am
getting the following link errors trying to link up a fully static
version of the code to use on other machines which have minimal dev.

`usual' not remade because of errors.
It looks to me like the gcc5 driver is looking in the wrong place for
some FORTRAN libraries, *OR* the operator forgot some link-time
incantations to make this work. This set of args works on another box on
my LAN, Linux, FC14 (soon to be updated to CentOS 6), Intel compiler
suite, FWIW. What do I need to do to get this to link ? TIA & have a
good one.
