No, we want to get away from compiling and linking directly.
That is what we use with Open Watcom F77 and C++.

The Watcom stuff is totally outdated.
Is there no way to get something newer ?

You must be new here in c.l.f.  Lynn has been converting
his 700 KLOC of Fortran to C++ for 2+ decades.  It seems
his code, which clearly isn't Fortran, can only be compiled
by a Watcom language compiler.  For those playing along,
that's roughy converting 140 lines of code per workday
with 2 weeks for good behavior (ie., 700000 / (50*5*20)).

 Don't forget maintenance (bug fixing) and user needed new features that require about 60 to 70% of our time.

And don't forget that we spent a lot of time updating the code by converting all of the Hollerith characters to character strings.  And adding "IMPLICIT NONE" to all of the subroutines requiring the explicit typing of all of the variables (maybe 10% were typed before due to extensive usage of implicit typing rules).
