OK, in that case, givaro_check.m4 is irretrievably broken and givaro
needs to provide pkg-config support which linbox can use instead.

givaro_check tries to link a test program against libgivaro0 simply by
including the givinteger.h header and this *was* a valid method for
older versions of givaro.

It definitely is - however, even if givaro migrates API, linbox will
still not get a valid result from givaro_check.m4. Givaro can help this
situation by providing a givaro.pc file.

There is no point thinking about uploading libgivaro1 without talking
to the release team who are unlikely to want a new transition at this
point. See #678769 - that's why I blocked this bug by #678769.

At this stage of the release freeze, the release team may be more
willing to consider removing givaro, linbox and fflas-ffpack.

This problem should have been noticed before the 3.7.0-1 upload. It is
difficult to fix now and you should talk to the release team about what
can be done and whether givaro can be released as part of Wheezy.
Currently, it looks unlikely.

Squeeze already has 3.2.13-1 which linbox can build against. Therefore,
it seems more appropriate to have no givaro or linbox packages in
Wheezy and let users pull in the working versions from Squeeze. True,
that means that users miss out on improvements in linbox since Squeeze
but that is the result of maintainers allowing libgivaro0 to migrate
into testing at version 3.7.0 when that should have been libgivaro1.
