that's fine - at the moment almost anything except 'arm-linux-gnu' is
"uncommon" with emdebian-tools currently, sadly.
In particular, the uClibc stuff is experimental in the full meaning of
the term. :-)

3) certainly does need to be applied and I will do so asap.

There may be a bug there - in dpkg or wherever - if gcc thinks that it
can create i486 when dpkg will not accept it. Probably a disjuncture
between gcc upstream and Debian dpkg maintenance.

Ah, yes, that's a typo. Thanks for spotting it, I will fix that in
1.1.6.

Is there a patch for that fix up? Is just changing the diversion name
really sufficient?

_all.deb ? I should have checked that - Simon, can the uclibc compiler
really be Architecture: all ???
