Thank you!

I've started to go through the svn trunk version of cbc and weed out
various warnings emitted by gcc. I'll probably send a patch about the
result soon, just a short question now:

The files

Cgl/src/CglTwomir/CglTwomir.hpp
Cgl/src/CglTwomir/CglTwomir.cpp
Osi/src/Osi/OsiCuts.hpp

use DBL_MIN, which is a bit suspicious for me. Doesn't they mean
-DBL_MAX instead? (DBL_MIN mean the smallest possible _positive_ double
precision floating point value.)

Regards,
Alpar
