This patch defeats the purpose of the module, which is "return current
directory with unlimited length". Some platforms have a PATH_MAX value that
is not a strong limit, but rather a dummy value because many BSD applications
don't even compile if PATH_MAX does not exist.

Can you limit the workaround to the platforms that need it, i.e. replace
"#ifdef PATH_MAX" with "#ifdef __sun" (or use an autoconf test)?
