(unsigned char) was the original cast but this is borken on some machines.
What's wrong with (unsigned)?  There are other places wher (unsigned) cast is
used.  I originally suggested to use the STOUC() macro but someone (rc?)
prefered (unsigned).  If the later works I'd prefer this (but I do not know
what's wrong woth STOUC()).  All of these should have the same effect in the
produced code (really these casting only affect what the compiler thinks about
the content of a register but (int)(unsigned char) misleads some compilers).
