Please add a comment explaining why we skip the tests. If there are no
tests, it can be as simple as "No test suite.".

Please use a complete sentence. For example, "This package provides a
very low footprint ...".

We should consider fetching the source with Git — these auto-generated
GitHub snapshot tarballs may change in the future.

Please add a code comment explaining this.

These sorts of mini-libraries are designed to be copied and pasted into
host projects rather than packaged on their own. That's why they don't
include a build system. For example, many cryptographic primitive
implementations are distributed this way — that's why you never see a
package for 'SHA256'. Is there a particular reason we should unbundle
pnglite?

The description was copied from upstream, but of course we can improve
it.

Well, I though we have a policy to remove bundle dependencies in order
to avoid building the same library many times. Do we make exceptions for
shared libraries w/o a build system? (an exception I can think of is
gnulib)

Besides, the FIXME comment seems to suggest future readers to help
remove the bundled pnglite. Debian also removes the bundled pnglite in
teeworlds[0].

Thanks for all the feedback!

In general, yes, our policy is to unbundle things when practical.

But there are some commonly used software implementations of basic
functions (like base64, sha1 (most hash functions actually), et cetera)
that are specifically designed to be copied and pasted into the
application that will be using them.

You can usually tell this is the case because the thing will not have
any build system at all, like you suggest. Also because you find the
same copy-pasted code in almost every program you look at, like with
base64 and the hash functions.

Well, at a certain point it becomes a matter of taste, and the choice
should be made by the person doing the work — you! Either way is fine
for Guix :) The important thing is to get this Teeworlds fix pushed
without too much delay.

Yes, we should get it fix fast :) I decide not to unbundle md5 because I
actually need to use a hack to make teeworlds build with libmd. But I
still have pnglite unbundle because it looks standalone enough for me
and no hacks are required to unbundle. Here are the new patches:
