Hi All,

I found a small bug in the header file gmp.h in line 2177.

(I have installed GMP&MPFR for using it them in CGAL)

The bug being that negative value being assigned to unsigned type, though this a subtle error I wanted to report it.

Error: unary minus operator applied to unsigned type, result still unsigned

This is what I got when I compiled my project.

Well, I am reporting this to GNU(as this is their code) as well, but I am sending this so that everyone can change the header file for correct output.

Thanks& Regards

Gopichand,
