**	This files can be seen as a list of everywhere gint relies on the
**	underlying OS. Although I wish to make gint free-standing, there are
**	still a few hard dependencies, namely:
**	* MMU management, because doing it wrong might break the calculator.
**	* Dynamic allocation, because we can't trash the system heap.
**	* File system, because it's a mess and we might ruin the ROM.
