breaks the MDAC Installation, no matter which version you attempt to install.
Reversing the patch fixes the bug(?). (I've also "downdated" actual CVS-Version
of loadorder.c to 1.16 - it works .. at least for the installer, though I don't
know what it breaks on the other end.)

I'm not really sure what exactly happens, the installer just says "Rolling back
MDAC .." assumingly just at the point where it's going to install the "Microsoft
XML parser".

If anyone likes to try to recreate the bug, you'll have to install IE, and  for
that you'll have to use Windows-Version Win98 and a NATIVE advpack.dll.
