clang doesn't work from cygwin-3.4.0 (Re: clang-format and clang-check return 127 and no text)

[ggl329]

In my environment, clang doesn't work as reported in
https://cygwin.com/pipermail/cygwin/2022-December/252719.html .

I found that it doesn't work with cygwin-3.4.0-1,
but works with cygwin-3.3.6-1.
cygwin-3.5.0-0.69.g8a003605c1df doesn't help.
Changes in cygwin-3.4.0-1 bring this issue?
or clang needs to be rebuilt?
