Is it really something that requires a rebuild of GnuCash?  I.e., if you
build GnuCash against 0.8.3 built with -nofastmath, but then drop in a
replacement 0.8.3 that was built WITHOUT -nofastmath, will GnuCash work
or not?

If GnuCash would work in this situation then I do not believe that it
should be a compile-time error because it also means the reverse could
be true.  An update from a working version of libdbi to a broken build a
libdbi would silently cause GnuCash to fail.

Is there a runtime test we can perform to see if it's broken?  Or is
there a way to work around the brokenness?
