The clang related issues might be fixed in 0.17; can you try that (or
git master)?

I'm not sure what the right answer is here. MATHPATHLEN (and PATH_MAX)
are not necessarily defined; in particular this would break
compilation on GNU Hurd. Perhaps we should ship a compatibility
implementation of a POSIX.1-2008 compatible [1] realpath. Or maybe
realpath can be avoided completely here.

Any reason not to use strncpy here?

Of course bug reports and fixes in any form are always welcome, but even
more appreciated if they roughly follow [2]; mainly patches from git
with sensible commit messages, and some minor coding style issues.

cheers,
