Gcc-3.4 holds back packages from testing?

[Andreas Tille <tillea@rki.de>]

Hi,

perhaps I missed something in my three weeks holidays but something
seems strange to me.  If I look at the nice extended graph for the
excuses available in PTS (MANY THANKS FOR THIS!) for instance of the
package xteddy I get

    ...

xteddy is waiting for libungif4, tiff

    * libungif4 is waiting for gcc-3.4
          o gcc-3.4 has release-critical bugs
          o gcc-3.4 is waiting for gcc-3.3
                + gcc-3.3 has release-critical bugs
                + gcc-3.3 is waiting for gcc-3.4

    ...

I wonder in how far gcc-3.4 is able to prevent packages from moving to
testing if it is not even in testing and packages should be builded with
gcc-3.3.  Anybody able to enlighten me?

Kind regards

         Andreas.
