No.  The most important word being `arbitrarily'.  For the vast
majority of the cases, it behaves equally well under both, and for the
very *pathological* cases, there is always a means to please both

I emphasize pathological because the guilty configure.ins were very
badly written, and any regular user of these tools would have said
it's badly written.
