As I noted in my report, the problem is dormant rather than truly gone.

I agree with you and Joss that AM_MAINTAINER_MODE is a good way to
prevent the recheck happening in the first place;
debian/patches/03_maintainer_mode.patch wasn't present in the 2.14.2
package in hardy-updates which I imagine is why the recheck still

Even so, it seems relatively fragile until and unless AM_MAINTAINER_MODE
is applied upstream as well. Relying on debian/patches/ to fix a problem
that manifests while applying debian/patches/ doesn't make me feel
right, although I suspect that in this particular case it would work.
For subtle misbuilds like this, I have to say I feel more comfortable
with fixing it in such a way that it still works even if the first line
of defence fails; passing the environment variable to 'make' guarantees
that even if a recheck happens for some unforeseen reason then it still

Thanks to you both,
