[gecode-users] compilation problem on windows + mingw32

[Mikael Zayenz Lagerkvist]

Hi,

I'm not very familiar with mingw, and I don't know if it can be made
to compile Gecode. Please note that Gecode requires at least version
4.2 of gcc.

Apart from that, the use of timersub can be removed simply. Please see
attached patch for the change needed.

Cheers,
Mikael
