Hello!
Can Cygwin gcc or clang be used to use ucrt instead of cygwin.dll/mingw.dll?
We provide a cross-compiler targeting the Win32 API, but this only
support msvcrt currently.

To avoid race issues, pthread::once() uses pthread_mutex. This caused
the handle leak which was fixed by the commit 2c5433e5da82. However,
this fix introduced another race issue, i.e., the mutex may be used
after it is destroyed. This patch fixes the issue. Special thanks to

Of course? How else would a lock work, it must release other waiters?
It might not be a fair lock though, which is not a problem for this situation,
which does not require fair locking.

Hello,
there are 3 coreutils versions in cygwin: 8.26, 8.32 and 9.0.
8.32 has a big bug on "cp" that leaks file descriptors. Copying many
files it dies with Too many open files.
9.0 has a bug that makes any chmod fail silently if it is applied to
