The patch is mostly adding new code guarded by #ifdefs based on the
Guile version.  So I think we can check and be reasonably confident
that the code effectively used when building against guile 2.0 won't
have changed much.  All the new code will be compiled out when
building against guile 2.0.  There may be bugs in the support for
guile 2.2/3.0 code, but that's a new feature, so it's better than
no support at all.
