[Snow-users-list] bug with snow + gambit + syntax-case + define-record*?

Has anyone been able to find anything out about this?  This seems like
a serious problem.  I can't use Snow if I can't use syntax-case.  The
only warning the Snow documentation gives about syntax-case is that it
isn't as portable as define-macro, but it should work.
