  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?
