No; what a lot of people want. Or rather, simply what is necessary.

What aspects of Windows' closed source cause difficulties? (As though 
people routinely trawl through Linux's tens of millions of lines of open 
source!)

Examples?

I've looked for a project simple enough, yet that can illustrate the 
problems I have. See https://github.com/jpoirier/picoc, a small C 
interpreter.

This has the usual makefile, that didn't work with the two make programs 
I tried, but looking at it closer, it's design to build for Unix. There 
is a project file for MSVC, but MSVC is a rather large and cumbersome 
download (actually, some 50,000 time bigger than the executable we're 
trying to build). And it probably wouldn't work, IME...

It turns out that building this app for Windows requires compiling and 
linking these 22 files:

  clibrary.c
  debug.c
  expression.c
  heap.c
  include.c
  lex.c
  parse.c
  picoc.c
  platform.c
  table.c
  type.c
  variable.c
  platform/library_msvc.c
  platform/platform_msvc.c
  cstdlib/ctype.c
  cstdlib/errno.c
  cstdlib/math.c
  cstdlib/stdbool.c
  cstdlib/stdio.c
  cstdlib/stdlib.c
  cstdlib/string.c
  cstdlib/time.c

Put them in a @file, and it's done. (The slashes have to be forward 
ones, otherwise gcc doesn't like it.)

I built it using bcc and gcc (tcc had a problem, which I may look at 
later, if only to compare the exes).

It can really be that simple. But I had to figure all this out by trial 
and error, when some suitable docs would have saved me some effort.

(It also needed this tweak, adding the stdint to the _WIN32 branch)

  /* host platform includes */
  #ifdef UNIX_HOST
  # include <stdint.h>
  # include <unistd.h>
  #elif defined(_WIN32) /*(predefined on MSVC)*/
  # include <stdint.h>
  #else
  # error ***** A platform must be explicitly defined! *****
  #endif

No, the developers just assume everyone else will use Linux, so whatever 
they themselves use to build can be bundled unchanged, and it will 
probably work, because whoever builds it will have the same ecosystem.

As for Windows, sometimes you see these MSVC project files bundled, but 
I've never found them helpful.

As I showed here, you don't need to run MSVC. And you don't really need 
the makefile; just a more suitable readme.
