Compiling C-Kermit 9.0.305 Alpha.02 on Cygwin

[Keith Christian]

I downloaded the .tar.gz of C-Kermit 9.0.305 Alpha.02, 19 September 2020.
Web page: http://www.kermitproject.org/ckdaily.html
Source download: http://www.kermitproject.org/ftp/kermit/test/tar/x.tar.gz

I realize that C-Kermit has not been in the Cygwin distribution for
awhile.  There is no "cygwin" target in the makefile in the x.tar.gz
source distribution.
Is there any guidance for how to compile this modern version of
C-Kermit for present-day Cygwin?

Thanks.
