Well, maybe we should tweak autoconf to add '-version' to the list of
options attempted.

But as for the "problem" of a noisy log file, this entire attempt to
probe versions is merely informational, and should in no way prevent the
rest of the configure script from using your compiler, regardless of
whether we were able to guess your compiler's quirks for outputting a
version number.

The only bug, if there is one, is that we should add one more option to
attempt in the loops for version probing in lib/autoconf/c.m4.
