Bug#389256: FTBFS with -O3: assembler symbols redefined

[Martin Michlmayr]

Package: sdlgfx
Version: 2.0.13-2

When you compile SDL_imageFilter.c with -O3 it fails because some assembler
symbols are defined.  This is because your sources define them but so does
the compiler at -O3.  According to the GCC people this is allowed, see
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29204 in which Andrew Pinski
writes "This is not a bug as asms can be duplicated even if they are
volatile.  The way to fix this is to use .1 and 1f lables."

Note that this is not a concrete problem in Debian since it's compiled at
-O2 but it would be nice if this could be fixed upstream.
