Version: 0.1.4
Severity: important
Tags: patch
libsvg fails to build on Hurd. There is no MAXPATHLEN in Hurd, because Hurd
doesn't impose path length limitations.
Please see failed build log:
http://buildd.debian-ports.org/fetch.php?&pkg=libsvg&ver=0.1.4-2&arch=hurd-i386&stamp=1191625588&file=log&as=raw
Patch attached below to correct this.
