1. Unless you actually use these functions in C code, then you don't
get load error?
2. If not in the installed header files, using them will be implicit
declaration, which is poor coding, right?

If I misunderstand, you don't have to explain.

Absolutely, but repint.h and repint_subrs.h declares extern functions
which should be available inside of librep, but it's inevitable, no?

Let me correct one, to make things sure. What were declared extern
were rep_file_gid / uid, not Ffile_gid. They have prefix "rep_", so
less polluting.

That you care is encouraging for us. We're absolutely short handed.
