[pkg-wml] Bug#653362: mp4h: FTBFS on hurd-i386

[Svante Signell]

Source: mp4h
Version: 1.3.1-6
Severity: important
Tags: patch

Hi,

mp4h FTBFS on GNU/Hurd, see
https://buildd.debian.org/status/fetch.php?pkg=mp4h&arch=hurd-i386&ver=1.3.1-6&stamp=1324166240

This is due to that MATPATHLEN is set to 256 in builtin.h which is far
too short for realpath usage. On GNU/HUrd PATH_MAX is not defined, while
_POSIX_PATH_MAX is and is set to 256 an that constant is used.

During the build of documentation mp4h.html from mp4h.mp4h the end of
the environment vector __envron is overwritten/truncated, removing the
NULL termination of that vector and causing a segfault. The attached
patch fixes these problems by dynamically allocating the resolved
pathname using the canonicalize_file_name() function if available. The
availability is checked in configure.ac. The patch should be placed last
in the series to apply properly.

Thanks!
