I just did a quick build on Ubuntu 10.04.4 LTS x86_64 with (my own build
of) GCC 4.7.0, without setting any `CFLAGS` or `CXXFLAGS`; `make check`
apparently passed without errors.
Only noticed that eclib's `configure` apparently doesn't yet check whether
the NTL and PARI installations passed to it really work; I used the ones
of some Sage 5.0.beta10 installation I also compiled with GCC 4.7.0, but
accidentally passed `--with-*=$SAGE_ROOT` instead of
`--with-*=$SAGE_ROOT/local` in the first place. While `configure`
succeeded with that, the compilation of course later failed, because
`<NTL/foo>` couldn't be included.
There should IMHO also be a `--with-gmp=...` option.

already see that in the code I call my div() functions mostly as ::div()
because of some similar clash, but have not before had a complaint about
the function declaration. I can see the point behind your "bad idea"
comment, but I have been happily using my div(int,int) and div(long,long)
functions for over 20 years, so I got there first!
Yeah, C++ didn't have namespaces (but neither templates) in 1990... ;-)
