Bug#754359: trousers: FTBFS on hurd-i386 and kfreebsd-any

[Svante Signell <svante.signell@gmail.com>]

Source: trousers
Version: 0.3.13-1
Severity: important
Tags: patch
User: debian-hurd@lists.debian.org
Usertags: hurd, kfreebsd

Hi,

trousers fails to build from source for GNU/Hurd and GNU/kFreeBSD due
to usage of HOST_NAME_MAX, which is not defined on these architectures.
The attached patch fixes this by using _POSIX_HOST_NAME_MAX instead
which is defined, including GNU/Linux. Alternately sysconf(3) could
have been used but a simple test program reveals that -1 is returned on
both Hurd and kFreeBSD.

Thanks!
