Nope.  memmove is in the C90 standard library, and glibc is only one
implementation of the C standard library.  I don't think SunOS 4 has a
fully ANSI-compliant C library.

SunOS 4 has bcopy.  Put this into the top (after the #include lines) of
the source files that don't compile

         static void *memmove(dst, src, len)
                 void *dst;
                 void *src;
                 size_t len;
                 bcopy(src, dst, len);
                 return dst;
