PTC.  But yes, I think GNU Tar has an option to override those, cygport
is just not using it yet.

Well, do not reset CFLAGS in your Makefile and cygport helpfully
provides all the scaffolding you need.  You might have noticed I
replaced the ":=" in your Makefile for exactly that reason.  A build
system is supposed to be able to pre-configure CFLAGS without your
Makefile nixing all of that effort.

It's generally considered bad form to provide a cygport file that
doesn't work standalone and the SRC_URI you provided only got me a 404.

You can rename the package after download by adding a "#new_name" to the
SRC_URI if you must.  I usually do that for patches that have
non-distinct names as I keep those files in a separate cache directory.
Otherwise if the SRC_URI has downloaded a file, that will get used for
the source package.

I generally keep cygport files under version control and I don't want to
rename the file for each release.  YMMV.

???  You must have renamed the cygport file to something else, I think.

No idea.

There likely is some script that uses bash.  Anything in your package
that uses something from a different package will create a dependency on
it (as it should).  This is not perfect and there are both false
positives and negatives, but in general it does work well enough.
Besides, bash is in Base anyway.

Just watch cygport --debug do it and then do the same.  But whatever you
do, please provide a cygport file that actually works when somebody
tries to run it.
