Generally, you should not touch those in the Makefile
of the application at all. When you build along with the rest
of DSLinux, the flags will already be set globally.
It is therefore usually enough to just make sure that
the Makfile does not modify them in any way. (Of course
there are exceptions to this for special cases, but
those rarely apply.) The same applies for other common
make variables, such as CC, CPP, CPPFLAGS, AR, RANLIB etc.

Are you referring to ?

The snapshot only contains a standard checkout, and nothing
that resides on special branches. You need to manually merge
files and directories from other branches if you need them.
(Again, see for more
information if needed.)

Wasn't it 8bpp? I'm not sure...

And feel free to ask further questions if there is trouble!
It's always great to see that more and more people are putting
effort into DSLinux. Thanks.
