At any rate; you're better off making your own version to begin with instead
of modifying a PBP library function.

If you attempt to install most PBP patches, they'll fail if you've modified the
library, and installing the latest PBP upgrade overwrites the library again, so
your approach was probably still the best one in the end anyhow..;o}

As Darrel pointed out, the library is there, and easy enough to modify. Just be
sure you know what you're doing, and make a backup copy before tinkering
with the original library file.
