[cfe-dev] [LLVMdev] Ninja build available for Visual Studio users

[Mikael Lyngvig]

A tiny question (I hardly know what Ninja is, but am looking forward to
trying it out): Does the changes also work with MinGW builds?  I've got a
Windows buildbot slave that does nothing but building LLVM+Clang using
MinGW64 all day, every day.  Or, is it only for Visual Studio?
