Actually, I would like to see an shlib bump before gcc is changed (so
that gcc and all binaries built by the new gcc depend on the new glibc).
However, I agree that it is currently a unfortunate time for such a
change.
So, some ideas come to my mind:
1. delay glibc upload until glib transitioned to testing
2. do another upload with shlib bump after glib transitioned to testing,
and wait with gcc to that upload.
(there might be better combinations, but none comes currently to my
mind)
Cheers,
Andi
