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.

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).
