gcc 4.3: LinBox package has broken NTL and givaro test

[mabshoff]

Okay, first off the current LinBox?.spkg from 2.8.2 needs some cleanups because there are unneeded files in patches that are just copied over. That causes the "NTL check for > 5" to fail. The other problem appears to be that givaro as well as LinBox? have different and probably incompatible gmp++.h header files. The current LinBox?.spkg also abuses CFLAGS, CXXFLAGS and CPPFLAGS and that is due to some bugs in LinBox?'s config system. I have fixed the issue for GMP and will also fix the problem for Givaro and NTL.

In addition two build fixes (1 by Saunders, 1 by me) have been proposed and should make it into svn fairly soon. I am currently stuck with the following:

Any ideas?

This has been fixed in LinBox? 1.1.5.
