Sorry, I don't want to do this. This might work now, but it does so
by pure luck, and might break in some future version of cmd, because
there _should_ be a space between /c and the command that follows.
The solution to this is simple: don't involve MSYS in building the
native port of Emacs. It boils down to removing MSYS from PATH in the
shell window where you run the build scripts.
