I've written two UDF libraries (one for blobs and one for guids) and
both were compiled using gcc cross compiling for windows on a linux box.
The secret is to use the "returns parameter x" methodology of
returning things.

If you use returns parameter x the server allocates the memory and
passes it to the udf. You can use whatever mechanism you want inside
the function as long as it clears up after itself.
