Bug#455407: FTBFS with GCC 4.3: #define redefined
Package: gdc-4.1
Version: 0.25-4.1.2-17d1
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
http://www.cyrius.com/journal/gcc/gcc-4.3-pedwarn.html
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.
