- EXT2/EXT3 file system support. - Does not yet support symbolic links or booting from an EXT2/3 partition. - Fixed bug in UI code. - Added '%%' format specifier to printf()-like functions. - Added functions __udivdi3 & __umoddi3 so that 64-bit division is now supported. - Changed types BYTE, WORD, DWORD, LONG, ULONG to U8, U16, U32, S32, U32 so that you know the size of the variable across different architectures with different sized words & dwords, etc. - Types CHAR, UCHAR, PCHAR, PUCHAR, WCHAR, PWCHAR have not been changed yet (I haven't decided exactly how I'm going to handle unicode) (isn't this an awesome commit? ;-) Just look at that list of files) svn path=/trunk/; revision=3318
