To answer the general question about 'should I file a PR about problems
due to compiling with clang?'

First check here: http://wiki.freebsd.org/PortsAndClang

That should contain results of compilation test runs.  If the port in
question is listed there, then the problem is known about, and you don't
need to report it[*].  Although if you can /fix/ the problem, then a PR
with patches is always welcome.

If your port isn't listed, then either there's something broken in your
local setup, or you're using some non-default combination of options or
otherwise doing something differently that exposes the bug.  If you've
made sure it's not the first case, then please do report it with details
of options settings or whatever else it was you did differently so
maintainers can reproduce and hopefully fix it.

Note that the exp-runs with clang generally pick up on compile-time
problems.  Run-time problems are a different matter and quite likely to
indicate problems with clang itself, something a lot of people are going
to be interested in getting fixed.

	Cheers,

	Matthew

[*] Unfortunately, the results of previous test runs building ports with
clang aren't available right now.  I think the servers in question are
still offline as a result of the security fun'n'games recently.
