[rrd-developers] HURD support, build fails, maybe an easy fix [patch]

[Daniel Pocock]

Package: rrdtool
Version: 1.4.7-2

I notice that the HURD build is failing with an error about PATH_MAX

This is a common issue.  PATH_MAX doesn't exist in HURD and it is very
trivial to work around

Full build log:

https://buildd.debian.org/status/fetch.php?pkg=rrdtool&arch=hurd-i386&ver=1.4.7-2&stamp=1343897555

Error:

Potential solution:

Attached is an example of a patch from another project, it appears easy enough to cut and paste into rrd_client.c
