Will stdcall default to cdecl?

Then I'd say the fault is clearly on the firebird side.

One last thing I'd try is to use another name (like with ld: using
-lmine is searching for "libmine.so", not only "mine.so"), if that
fails, too, it time for one of fpc's developers to comment or the
firebird people to investigate.
