Discussion:
What's different on your machine vs. the passing builds in our Azure CI matrix?
Probably the installation paths. My hunch is that MSVC is now receiving extra quotes, due to `CCompiler.spawn` having a poorly-designed contract (one that we don't own) when passed lists. I assumed that the list semantics were an extension for our own use, but it looks like they're relied upon in `distutils._msvccompiler`.

Basically, `CCompiler.spawn(['"C:/Program', 'Files/program.exe"'])` seems to be required to behave the same as `subprocess.call(["C:/Program Files/program.exe"])`, which is pretty alarming to me.


https://bugs.python.org/issue8987 is related here, but it looks like distutils is destined to be broken forever, for fear of breaking people who are working around the bugs.
Removing our patch to `gen_preprocess_options`, which causes arguments to be double-quoted, seems to solve the issue. In fact, I think every instance of `quote_args` probably needs to be removed from `numpy.distutils`.
