    testsuite/108604 - gcc.dg/torture/pr108574-3.c hangs on unsigned char a=
rchs

    In the architecture where sign defaults to unsigned, the 'f' will be ze=
ro
    extended to int type in the expression 'd =3D ~(f & ~2880764155)', then=
 the
    'd' will become -1 wich cause the case to fail.
    So it's ok for the architectures where sign defaults to signed like x86,
    but failed for the architectures where sign defaults to unsigned like a=
rm
    and csky. Change char to signed char to avoid this problem.
