Well yes, but you seemingly didn't compile Samba in the same way as
your original installed Samba.

And mine.

Whilst this sounds very easy to do, to do it correctly you would need
to know just where 'process_prefork.c' ends up, what particular part of
Samba uses it, once that is known, you could just replace that
particular piece of Samba, provided everything else is compiled exactly
in the same way, I don't think that would be easy. The easiest way
would be to rebuild your distros Samba package sources using your
slight change and then install the resultant Samba packages over your
install.
