Bug#558586: hyperestraier: FTBFS on hurd-i385: unconditional usage of PATH_MAX

[Pino Toscano]

Package: hyperestraier
Version: 1.4.9-1.4
Severity: important
Tags: patch
User: debian-h...@lists.debian.org
Usertags: hurd

Hi,

as shown in [1] (even if for version 1.4.9-1.3), currently hyperestraier does
not build on GNU/Hurd. The problem is the unconditional usage of the PATH_MAX
constant, not POSIX.
The easy fix is to malloc+free the two buffers currently stack-allocated of
PATH_MAX size; patch attached.

Thanks,
