There is a new Cygnal beta, version 18.104.22.168. This is based on the
3.1.7 baseline of Cygwin, plus a few commits cherry-picked from
upstream to get 3.1.7 to build under current Cygwin (mostly due
to GCC 10 diagnostics).
See here for the links to the pre-built DLL binaries and git branch:
I have made some improvements to the web page. The git repository now
has all the upstream tags also.
