Bug#636568: xerces-c: Fix FTBFS on hurd-i386

[Svante Signell]

Package: xerces-c
Version: 3.3.1-1
Severity: important
Tags: patch
User: debian-h...@lists.debian.org
Usertags: hurd

Hi,

currently xerces-c does not compile on hurd-i386. The problem is a
PATH_MAX definition which is not supported on GNU/Hurd.

One of blahtexml build dependencies is xerces-c. blahtexml is on the
list of GNU/Hurd packages lagging behind other architectures:

The attached patch fixes the build. 

Thanks,
Svante
