PATH_MAX is only mandated by POSIX if there is a system limit for the
maximum path length.  This is not the case on GNU/Hurd, that's why this
code fails.

As this is appears to be only in a test file, I suggest to simple
#define PATH_MAX to an arbitrary value if it is not #defined already. 

Patch attached, please apply (as libxml2 blocks quite a couple of other
packages) and proxy upstream at your discretion.


thanks,

Michael
