Package: gcc
Version: 2.7.2-5

This bug is the one that the people have been seeing who have been
trying to compile dpkg using GCC 2.7.2 (ELF or M68K).

The next version of dpkg will not compile dselect/main.cc (the
problematic file) with -O3, instead using -O2 for most files, so this
will no longer be a problem for dpkg.

Ian.

Subject: GCC -O3 produces unsatisfied external ref to static function

Package: gcc
Version: 2.7.2-5

This bug is the one that the people have been seeing who have been
trying to compile dpkg using GCC 2.7.2 (ELF or M68K).

The next version of dpkg will not compile dselect/main.cc (the
problematic file) with -O3, instead using -O2 for most files, so this
will no longer be a problem for dpkg.

Ian.
