           Summary: [patch] Fix build on Hurd without PATH_MAX
          Severity: normal
    Classification: Unclassified
                OS: other
          Reporter: pere at hungry.com
          Hardware: x86 (IA32)
            Status: NEW
           Version: unspecified
         Component: server
           Product: Spice

The following patch fixes the server build on Hurd, where PATH_MAX is not
available.  With the fix, all the server part of spice builds on Hurd.

I'm also looking at the client part, but it require thread features I do not
yet know on Hurd.
