Just have init_progfile_dir() take a void pointer.

dladdr() takes a void * as a code pointer; have init_progfile_dir() do
so, and do the casting in the calls.  We don't care about the signature
of the function whose address we're passing, we just want to pass a
pointer to *something* in the main program.
