Further research prooved, that the AIX linker eliminates functions on a per
c file basis if none of them is referenced elsewhere (declared extern or not).
Thus it eliminates the whole conv.c file from the postgres executable since
those functions are only used by the conversion shared objects.

Anybody have an idea what I can do ?
