scm_i_init_rstate vs gcc-3.4

Someone who knows what this bit of code is meant to be doing can
check:

        * random.c (scm_i_init_rstate): Compare w to -1 not 0xffffffffUL, now
        that it's an scm_t_int32.  Otherwise gcc 3.4 says it's always false on
        a 64-bit system.

(This gcc complaint is a warning, but warnings are made fatal of
course.)
