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:
http://ftp-master.debian.org/users/twerner/pre-squeeze.txt

The attached patch fixes the build. 

Thanks,
Svante
