Add char* cast to avoid compiler warnings

In libc-client 2007f `data` is declared as `unsigned char *`; there may
be variants which declare it as `void *`, but in any case picky
compilers may warn about a pointer type mismatch in the conditional
(and error with `-W-error`), so we're adding a `char *` cast for good
measure.
