Heads up: gui-wm/wayfire requires now sys-devel/gcc[openmp]

As the title says >=gui-wm/wayfire-0.9.0 does not compile (even fails to configure) when openmp is disabled on sys-devel/gcc.
This took me quite a while to detect, because I have a machine with only a single core which for this reason had -openmp globally.
I will not report a missing dependency on bugzilla, because adding dependencies on a particular compiler or compiler options appear to be wrong; probably not many people will run into this, anway.

You should, because:
a) there is a build system option for openmp which should be wired up;
b) there's a mechanism for at least detecting if the current compiler has OpenMP support and giving a nice message if not.

Even if you choose not to follow sam_'s request to report this, please post the specific messages that indicate this is the cause of the failure, so that future readers searching for that error will be led here.

Hm. I wonder how systems with llvm toolchain and no gcc will fare in compiling wayfire..?

LLVM has libomp.

OP's reported it at bug 940040.
