Bug#762673: emboss: FTBFS on hurd-i386

[Svante Signell]

Source: emboss
Version: 6.6.0+dfsg-1
Severity: important
Tags: patch
User: debian-hurd@lists.debian.org
Usertags: hurd

Hi,

Currently emboss fails to build from source due to usage of
PATH_MAX, which is not defined on GNU/Hurd. Only one file needs a
modification, see the attached path. This patch assumes getcwd(NULL,0)
works. Depending on for which systems this software is aimed at, a
configure.ac (.in here) check can be added. However, it seems that
upstream is not very active lately. This patch should work at least for
Debian supported OSes (libc4, libc5, glibc).

Thanks!
