Description C.W. Betts 2015-11-06 22:30:45 UTC 
Swift is very strict with types, so much that those of different signedness/size must be cast. Most of the defines are imported as 32-bit signed integers, while the corresponding field in a struct is a 32-bit unsigned integer. Appending a "u" would cause the defined types to be imported as 32-bit unsigned integers.

Add u to defines

This patch changes all the define constants to end with a "u", making them import into Swift as UInt32.
