cast missing in rtl.c

[Peter Schmid]

While building egcs-980115 I get the warning 
gcc -c  -DIN_GCC   -DUSE_GNULIBC_1 -g  -DHAVE_CONFIG_H      -I. -I.
-I./config rtl.c 
rtl.c: In function `read_rtx':
rtl.c:668: warning: initialization from incompatible pointer type

The following patch silences this warning.
