#define ALIGN4   __attribute__((aligned(4)))

Force word alignment.

In the old days, GCC aggregates were always word aligned. In the EABI environment (devkitPro r19 and higher), they are aligned to their widest member. While technically a good thing, it may cause problems for struct-copies. If you have aggregates that can multiples of 4 in size but don't have word members, consider using this attribute to make struct-copies possible again.

#define DEPRECATED   __attribute__((deprecated))

Deprecated notice.

Indicates that this function/type/variable should not be used anymore. Replacements are (usually) present somewhere as well.

#define INLINE   static inline

Inline function declarator.

`inline' inlines the function when -O > 0 when called, but also creates a body for the function itself `static' removes the body as well

#define PACKED   __attribute__((packed))

Pack aggregate members.

By default, members in aggregates are aligned to their native boundaries. Adding this prevents that. It will slow access though.
