I believe DRM is not available for windows, so this exceptions seems to make it impossible to build 11.1 under windows.
The following commit should fix it. I'll scoop it up for the next 11.1 release. commit 02afbd247620bd51a5b1661ced9b01a865136484 Author: Jose Fonseca <jfonseca@vmware.com> Date: Sat Nov 21 21:19:57 2015 +0000 scons: Conditionally use DRM module on pipe-loader. Fixes non Linux builds. Trivial.
After I apply the changes of that patch to the src/gallium/auxiliary/pipe-loader/SConscript file, scons starts, but ends in a compile error: rc\gallium\auxiliary\pipe-loader\pipe_loader.c(83) : error C2065: 'PATH_MAX' : undeclared identifier rc\gallium\auxiliary\pipe-loader\pipe_loader.c(83) : error C2057: expected constant expression rc\gallium\auxiliary\pipe-loader\pipe_loader.c(83) : error C2466: cannot allocate an array of constant size 0 rc\gallium\auxiliary\pipe-loader\pipe_loader.c(83) : error C2133: 'path' : unknown size rc\gallium\auxiliary\pipe-loader\pipe_loader.c(91) : warning C4034: sizeof returns 0 rc\gallium\auxiliary\pipe-loader\pipe_loader.c(95) : warning C4034: sizeof returns 0 rc\gallium\auxiliary\pipe-loader\pipe_loader.c(98) : warning C4034: sizeof returns 0
Looks like the we also need commit 4befd82a649 "pipe-loader: Fix PATH_MAX define on MSVC.". I've scooped both for 11.1.2 which should be out in a few days.
