Explanation: Prevents compiler warning about possible loss of data.
This compiler seems quite dumb :-) How can (n & 0xFF) loose data??
 Being charitable [1], *technically* you are potentially losing
information---values 128 to 255 may become -128 to -1, if chars are signed
[2].
 -spc (Or it could be an utterly stupid compiler)
[1]	Like Microsoft needs any charity
[2]	C standard leaves the signness [3] of a bare 'char' declaration up
	to the implementation---it can be either signed or unsigned.
[3]	Is that even a word?
I think signedness is a word... (don't ask me tho, idk)
