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!
