Fix build of boost-libs in NetBSD/macppc: 'char' is not signed, so a piece

of code was raising warnings and failing to build.  Changed to use 255 for
error conditions instead of -1, along with unsigned chars unconditionally.

+A 'char' cannot be expected to be signed.  PowerPC, for example, defines
+the 'char' type as unsigned.  Fix this piece of code to not deal with
+signed characters.
