If nothing else, the autoconf philosophy of feature checks being better
than version checks should guide your decision here.

What _specific_ feature are you using from 1.12 that wasn't present in
1.11?  Or put another way, either your works equally well
with both versions (so you don't care which version), or there's
something you do with 1.12 that doesn't work with 1.11 and therefore you
are trying to make it conditional so that 1.11 can still process the
rest of the file.  Determine that feature, and we are that much closer
to helping you conditionalize your to work with both versions.
