0.9.0.3:
	Fix a few leakages from the host environment that only mattered
        when the host compiler had a larger fixnum size than the target.
        Building a 32-bit SBCL with a 64-bit SBCL as host should now work.

        * COMPACT-INFO-LOOKUP FIXME fixed by LOGANDing the return-value
          of GLOBALDB-SXHASHOID with SB!XC:MOST-POSITIVE-FIXNUM
        * Some !constants (LAYOUT-CLOS-HASH-MAX, CALL-ARGUMENTS-LIMIT,
          etc) were derived from MOST-POSITIVE-FIXNUM. Use
          SB!XC:MOST-POSITIVE-FIXNUM instead.
