Although C++ compilers may be available, they (or their libraries) are
not necessarily installed properly, and this can be a problem at runtime
as well as at compile-time. So it may be better to stick with C if it works.
OK, let's keep the code as is for now; once we find a platform that causes problems, we can reevaluate the options.

Ah, that's key. Although 'configure' suppresses that false alarm if
--enable-gcc-warnings is specified, it also needs to suppress it when
--enable-gcc-warnings is *not* specified. I installed the attached,
which I hope fixes the warnings that were annoying you (assuming we are
not using -save-temps, which is a reasonable assumption).
OK, thanks.
