I don't think this is true. Surely if it was it never would have made it into Guile, right? I mean... this is GNU we're talking about here and psyntax has been around awhile! Having been immediately nerdsniped by this email, I had to quickly do some research. A 'git blame' dates the quoted license text back to 1998, commit a63812a2fef2f81b8c4eca04c858e42b62e455f9, by Jim Blandy. Commit message: Talked to Stallman. Actually, the syntax-case copyright is no problem. Duh. * Makefile.am (ice9_sources): Revert last change. * syncase.scm, psyntax.pp, psyntax.ss: Added again. * Makefile.in: Regeneretade. This confirms my hunch that there is no issue with the license. - Dave
