Bug#456084: FTBFS with GCC 4.3: #define redefined

Package: kdebase
Version: 4:3.5.8.dfsg.1-2
Usertags: ftbfs-gcc-4.3

Your package fails to build with GCC 4.3.  Version 4.3 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning.  GCC 4.3 has converted a number
of warnings into errors.  With GCC 4.3, you're no longer to
just redefine a previous #define.  You need to either avoid
redefinitions directly or to use #ifndef to make sure that something
has not been defined already.  See

You can reproduce this problem with gcc-snapshot from unstable.  Note
that Red Hat, Novell and Ubuntu have done some work getting packages
to build with GCC 4.3 so there might be patches floating around
somewhere.  I suggest you talk to your upstream.
