Hi,

This patch solves the build problems for GNU/Hurd due to PATH_MAX
issues. The solution is to make dynamic string allocations instead of
using fixed length buffers. The patch involves one file, and is
trivial. Parts of the code have been reviewed by GNU/Hurd developers
and Debian GNU/Hurd developers and maintainers.

FIXME:
Is it really useful to check if BUFSIZ is defined?

TODO:
Should the "whole package" be tested with valgrind on GNU/Linux?!
If yes, is there a standard procedure to do it?!

Thanks! 
Special thanks to Jérémie and Richard for their comments!
