I just (well, nearly 2 hours ago!) downloaded the sources for gcc. It

Whatever you downloaded, it wasn't (just) the sources for gcc.
The latest release of gcc (14.2.0) has 58503 .c files and 4131
.h files, and the gcc project does not make it available as a
.zip file.  When you say "the sources for gcc", I presume you're
referring to some software package that includes gcc.  Why didn't
you mention that?

So you just assumed that's official.

Someone else has already replied and told you where the official gcc
source code resides.

You assumed it's on GitHub.  It isn't.  Not everything is.  The GNU
project does its own hosting.  Somebody apparently decided to set up a
mirror on GitHub, but I wouldn't rely on it.  And it might not be up to
date with the official gcc git (not GitHub) repository (though it
appears that it is).

That zip file is the latest version on the "master" branch, *not* a
release.  It isn't necessarily stable.  But if your goal in downloading
and extracting it was to make a point yet again about how difficult it
is for you, I suppose that doesn't matter.

If you wanted the gcc sources for a given release, it would be better to
download a .tar.gz or .tar.xz file from an official mirror, which you
can find via gcc.gnu.org.  GitHub's zip download feature just gives you
a snapshot of the repo, *not* an official release.  A build procedure
that works with an official tarball might not work with a git snapshot,
for reasons I won't go into here.

Yes.

The big thing everybody lauds gcc for is the range of targets it
supports. But not supporting that obscure target called Win64-x64 is
fine!

It's fine with me.  If it's not fine with you, complaining about it here
is unproductive and off topic.  (And a "target" is the system for which
gcc generates code, not necessarily the system on which gcc runs.)
