You did ask for compatibility :-)
Johannes Waldmann's suggestion may be relevant:

: "brackets is now called angles, while squares is now called brackets."

I'm guessing that you're explicitly overriding the -P parameter.
The trick here is to say ";newdir", so it adds your new directory
to the standard ones (which are different between -N and +N).
(I think -- I don't know about the Windows interface.)

You want the search path to be something like

	{Hugs}\libraries;{Hugs}\oldlib;{Hugs}\lib\win32

with any other directories added on the end.
