If the application isn't doing some really weird stuff, I seriously
doubt it.

Actually, no.  What cygport really does is this:

- create binaries with debug info
- create debug info files from the non-stripped binaries and copy
  them to usr/debug/...
- strip the binary and pack it into the base package "foo"
- pack the debug info files into the debug package "foo-debug"

So, a user of the package gets just the smaller stripped foo binary,
while a developer can install the foo-debug package and actually
debug the foo binary.

Yes.  Plus generating the debug info package.
