The content of configure is high-level human readable source code. But 
it is meaningless.

Well, while we're here, why don't /you/ run configure and tell me what 
the output is. Preferably in a form I can understand.

Here's the input data:

  OS:        Windows 7
  Processor: Intel 64-bit

Um, that's it I guess. I only need enough info to build, say, 
python.exe; just something to get to first base. (I don't know what the 
other binary files are or where they live.)

(I have visions of you now feeding a punched card into a computer called 
Multivac occupying a cubic mile of vacuum tubes and relays... That's 
about the same degree of overkill!)

Yes! That's what I need!

But either this information is highly classified, or nobody here 
actually knows how to extract it from the output of configure or the 
makefile or wherever it ends up.

Or, more importantly, how this list of files could be determined manually.

Once again, this is not for development. It's a one-off build of a fresh 
download, so everything will need compiling anyway.

Has someone thought about replacing it then? I would be nervous about 
running 20000 lines of AI-generated code that manipulates my file system.

Yes. The end-result of all this might be something like:

   gcc -c file1.c
   gcc -c file2.c
   gcc file1.o file2.o ... -opython.exe

Someone please explain why I can't just do that
