The problem is this:  We don't have a clue under what circumstances
this message is printed.  We know *why* it's printed, but none of
the core maintainers and none of the package maintainers seem to have
a system which suffers from this problem.

I already wrote two mails on this to this list.  I'm running Windows
8.1 32 and 64 bit, but on my machines, the find_fast_cwd warning is
not printed, so the find_fast_cwd mechanism works as expected.

To get rid of this message, either I have to know how to reproduce it,
or somebody with this problem would have to debug a teeny little bit
of assembler code inside the Windows ntdll.dll file.

To be able to reproduce it, I would need somebody who can reproduce the
problem and being prepared to experiment a bit.  It *seems* the problem
is introduced by some Windows update package which is not installed by
Windows Update by default.  If we can find out which package this is,
I could debug this and get rid of the message.

But, alas, nobody has offered to help so far.

In your MingW environment, you're probably using the tools from MSYS2.
MSYS2 is just a copy of Cygwin with a few tweaks for easier integration
with a native MingW toolchain.  MSYS2 is using the find_fast_cwd code
as well, so you're getting the same warning.

The Cygwin remnant is probably MSYS2.  Other than that, if somebody
would take a heart trying to find out what introduced the problem on
his or her machine, we could eventually get rid of it completely.
