which officially fixes the setuid security exploit by the vendors.
Additionally, from the PR:
* adds in distribution patches to allow it to interoperate
with libtiff-3.5.5 (the current version in the ports tree),
and replace an original FreeBSD patch.
* includes security patches (replacements of 'strcpy' and
'sprintf', primarily), mostly based on patches originally
submitted by Alex Langer [1] for 4.0pl2 and not yet commited,
although some new work was done too.
[1] I don't think, that these were my patches but those submitted by
John Holland <john@zoner.org> in PR 19180.
* Fixes some issues with the configure/setup scripts introduced
since the previous version.
* Additionally, original FreeBSD patches from 4.0pl2 were
merged in where they were not addressed by anything else.
(except the I18N patch, sorry).
I removed the FORBIDDEN line since there are at least no obvious security
concerns left.
