Hi branches/gbuild-reintegration has been merged to trunk. It has > 136 patches and makes many changes throughout the code, so you probably need to "dmake clean" before rebuilding.
I haven't fixed the Windows build performance regression caused by issue #117845, so if you're building on Windows use --disable-pch which only extends your build time by around 2 hours instead of 6. If you aren't happy with this, please help me figure out the problem. Damjan
