It does quite a bit more for you to check and setup up the build environment.

It makes applying the patches easier, especially if you get them from an 
upstream distro like Fedora:
	https://cygwin.github.io/cygport/cygport_in.html
documentation on Preparation stage between Downloading and Compiling:

	https://cygwin.github.io/cygport/src_prep_cygpart.html

GNU patch 2.8 is now available and should be updated soon in Cygwin:

	https://savannah.gnu.org/projects/patch

	https://ftpmirror.gnu.org/patch/

You can clone the cygport repo:

	https://cygwin.com/git/cygwin-packages/patch

change the version, update the Fedora patch sources to F42:

	https://src.fedoraproject.org/rpms/patch/raw/f42/f

comment out all the patches:

https://cygwin.com/git/?p=git/cygwin-packages/patch.git;a=blob;f=patch.cygport

probably also the autoconf version, and SCALLYWAG test suppression; then run:

	$ cygport patch.cygport get all

and it may well build you a nice new version of patch, with all the build logs 
under patch-2.8-1.x86_64/log/, the install tree under .../inst/ and the tars 
under .../dist/, etc.
