To install the last cygwin version for x86, run setup using the options 
'--allow-unsupported-windows option --site circa_URL', where circa_URL 
can be one of:

* The URL for any sourceware mirror[1], followed by cygwin-archive/20221123


Thanks to the Cygwin Time Machine for providing this archive.

These instructions have also been added at [2]

sourceware (but the list at [4] is believed to be sadly incomplete)
