Then you've got to get Visual Studio Community Edition and follow the horrendously complicated instructions that I gave previously.  It is impossible to do this unless you have at least five PhDs, all of which must be in completely different subjects.  Come on you lot, own up, who didn't realise I was that smart?

There's another little flaw I forgot to mention.

The purpose of the test a few posts up was to get an idea of how fast 
CPython might be when compiled with something like Tiny C, compared with 
compiling it with gcc (on Linux) or MSVC (on Windows).

I've already got a working CPython binary to measure; I need the same 
version built with Tiny C to compare.

Unfortunately downloading Visual Studio is not really going to help with 
that. Good thing I remembered in time.

(Whether it is possible to build CPython with an alternative compiler, 
I've no idea. I suspect that the source code has dependencies on both 
gcc and MSVC. In other words, there will be conditional paths for gcc 
(or clang which is a clone) and MSVC, with no other possibilities.)
