1660         * sb.c, macro.c: Include string.h.

1662         * Makefile.in (comparison): Only check *.o; we don't care if

1664
1665         * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
1666         if alignment stricter than 4 bytes is requested; in that case,

1689         * config/tc-m68k.c (isword): Accept all values from -65536 to
