I believe the answer you got from SFLC ("no") contradicts what the
authors of the GPL say about this case. viz:
"You have a GPL'ed program that I'd like to link with my code to build
a proprietary program. Does the fact that I link with your program
mean I have to GPL my program?
Not exactly. It means you must release your program under a license
compatible with the GPL (more precisely, compatible with one or more
GPL versions accepted by all the rest of the code in the combination
that you link). The combination itself is then available under those
Furthermore, GNU publishes a list of licenses that are compatible with
the GPL, and that list includes BSD3 and MIT/X11.
