* now we have seperate private headers files containing private and static or public functions in memory-* files. * there is only one .c file of the same name the library. Zagor: because now there is only one .c file, you could only have a .o file and use it instead of the .a libfile. * most structures and codes are now private. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@112 a1c6a512-1295-4272-9138-f99709370657
