Glad to hear that the module 'posixcheck' still works fine! (I haven't
actually used it for more than 10 years.)

It would be helpful to show the actual link command, not an abbreviation
such as "CXXLD". That is, run "make V=1", not "make".

For analyzing a .a file, please use 'nm', not 'strings'. Especially
"nm libgroff.a | grep ' T '" and
"nm libgroff.a | grep ' U '".

Likewise.

It should work also with these modules included.
