[PATCH 0/4] Fix 4store on Hurd.
This series of patches should allow 4store to work on Hurd.
The first patch defines HOST_NAME_MAX to _POSIX_HOST_NAME_MAX, which should always be defined on Hurd.
The second patch makes sure sys/statfs is included instead of sys/mount.h when compiling for Hurd.
The last two patches deal with a PATH_MAX issue in a way that should be portable.
All patches are against the GIT repository (git://git.debian.org/git/collab-maint/4store). After applying them, make and make check can be run successfully.
