That's what I did with the Karl's regex wrapper, which crashes when 
translated due to this problem.  I made a middleman dll as we talked 
about last time that simply passes through the parameters to the real 
dll, and then passes back the result.  Works fine. I'm going to make 
another for the SQL-Lite library, which has the same problem.  I used 
the BCX basic to c translator with LCC.  Using that, you can make your 
middleman .dll in just a couple of minutes.  I'll post the method if 
anyone is interested.

I don't know of way to make a universal one -- you have to put in 
equivalents for each individual function. You also have to add one extra 
initialization function, so the first .dll will open up the second one.

If you need to set up callbacks back to a Euphoria routine, I have no 
idea how to do that...
