Re: #include <stdio.h> on Android clang causes an error

[Lucy Phipps]

this works, but there's an additional warning now:
/home/builder/.termux-build/gzip/src/lib/free.c:48:3: warning:
implicit declaration of function 'free' is invalid in C99
[-Wimplicit-function-declaration]
  free (p);
  ^

the only 2 warnings before were in strerror_r.c:
/home/builder/.termux-build/gzip/src/lib/strerror_r.c:205:9: warning:
incompatible pointer to integer conversion assigning to 'int' from
'char *' [-Wint-conversion]
    ret = strerror_r (errnum, buf, buflen);
        ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/builder/.termux-build/gzip/src/lib/strerror_r.c:242:60: warning:
comparison between pointer and integer ('char *' and 'int')
[-Wpointer-integer-compare]
        if (strerror_r (errnum, stackbuf, sizeof stackbuf) == ERANGE)
            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^  ~~~~~~
