[Pkg-gnutls-maint] Bug#405239: libgnutls13: gnutls13 has an unnecessary dependency on libgpg-error

[Nathanael Nerode]

Package: libgnutls13
Version: 1.4.4-3
Severity: normal
Tags: patch

gnutls appears to have an unnecessary dependency on libgpg-error;
gnutls does not appear to use anything from libgpg-error directly.
With this dependency eliminated, it should no longer be necessary
to rebuild gnutls if libgpg-error changes ABI.

See http://rerun.lefant.net/checklib/ for background and further
information.

I believe this (untested) patch should do the trick; the dependency
is dragged in by the ill-behaved libgcrypt-config.  (It may in fact
be dragged in by something else too, but this is a start.)

It will be necessary to rerun aclocal and autoconf after changing
this.  And possibly other autotools.  And of course ship the
changed configure.in.
