and the install target then creates a bunch of (IMO) debug junk in
/usr/lib/debug and /usr/src/debug.
Debuginfo is not "junk". Like most Linux binary distros, these files
are automatically packed into a ${PN}-debuginfo package and excluded
from other (sub)packages without further intervention by the maintainer.
Users can then install gdb and these debuginfo packages to debug
software in place, without having to install BRs and rebuild packages.
Is this a change that's been made recently in cygport?

Can it be easily turned off?
Yes, it can, as described in the manual, but the only time you should is
if you are trying to debug a package in its build-tree (e.g. noinst
test/example apps), and then only temporarily, e.g.:
RESTRICT=debuginfo cygport foo-1.2.3-1 build
I grepped through /usr/share/cygport for that, and found that
compilers.cygclass uses it, but I don't include that in my cygport script
(below).
You mean compilers.cygpart; .cygpart files are just the main cygport
script functions broken up into manageable sections, like .c files which
are compiled into an executable. .cygclass files are optional "modules"
which are imported with inherit().
It's been discussed quite a bit on cygwin-apps. See, for instance, the
thread starting at
http://cygwin.com/ml/cygwin-apps/2012-06/msg00071.html and continuing
into July. If you don't want to provide a debuginfo package, put
"_CYGPORT_RESTRICT_debuginfo_=1" in your .cygport file.
Bzzzt. Don't use internal structures. If it's not documented in the
manual, you shouldn't be using it in your .cygport, and anything
starting with an underscore is purely internal.
But again, while I can't state this as policy, you really shouldn't be
disabling debuginfo on a widespread or permanent basis. It's a feature
and it's there for a reason.
