This was working before I upgraded Cygwin:

$ clang --version
clang version 8.0.1 (tags/RELEASE_801/final)
Target: x86_64-unknown-windows-cygnus
Thread model: posix
InstalledDir: /usr/bin

$ clang-format.exe --version
clang-format version 8.0.1 (tags/RELEASE_801/final)

$ uname -a
CYGWIN_NT-10.0-19045 AMDAHL 3.3.5-341.x86_64 2022-05-13 12:27 UTC x86_64 Cygwin

But it doesn't work anymore with

$ uname -a
CYGWIN_NT-10.0-19045 AMDAHL 3.4.3-1.x86_64 2022-12-16 12:38 UTC x86_64 Cygwin

(same symptom as https://cygwin.com/pipermail/cygwin/2022-December/252719.html)

Additionally,

$ strace /usr/bin/clang --version
strace.exe: error creating process C:\cygwin64\bin\clang, (error 5)

$ gdb -q /usr/bin/clang -ex run

0xC0000139 is "Entry point not found"
