These are good points. I think that you are right about the characteristics
of my compiler, but this is a standard linux system.

The relevant output from make is:

(cd .libs && gcc -c -fno-builtin -fno-rtti -fno-exceptions "etherealS.c")
rm -f .libs/etherealS.c .libs/ethereal.nm .libs/ethereal.nmS .libs/ethereal.nmT

If something wrong is happening (and I am not sure that it is) then
the configure script may need looking at.

I will check a number of points and answer all these issues later today.

Ben.
