Dear ghc devs My Windows build failed as below, because it couldn't find gcc. But this is the ONLY reason we need gcc! GHC and its libraries all built without gcc, perhaps because we use ghc itself to compile C files, and ghc has a C compiler in its belly (no PATH reqd). Question: would it be possible to use the same technique to compile timeout, so that we don't need to install gcc separately? This is on Windows. Thanks Simon Building timeout-1...
