patch for darwin/macosx-publicbeta

Follows is a tiny patch to make top of tree compile up to the IPC section
on Mac OS X Public Beta. I have not yet chased down what will be needed for
IPC, but this patch corrects a incorrect return type in the dyloader code
to match how the qnx and hpux files use PGFunction. This also fixes the
Makefile to use a tab instead of 8 spaces. (please make sure it is patched
as a tab!)
