Bug#758890: lua-filesystem: FTBFS on hurd-i386

[Svante Signell <svante.signell@gmail.com>]

Source: lua-filesystem
Version: 1.6.2-1
Severity: important
Tags: patch
User: debian-hurd@lists.debian.org
Usertags: hurd

Hi,

lua-filesystem fails to build from source on GNU/Hurd due to MAXPATHLEN
usage in src/lfs.c, which is not defined. Since the source comment says
that getcwd(NULL,0) is not guaranteed to work, use _POSIX_PATH_MAX as a
last resort. The attached patch fixes this problem. Additionally the
six tests pass enabling the packages to build.

In case the package had been using configure a test for a working
getcwd (NULL, 0) could have been included, and the source modified
accordingly.

Thanks!
