Subject: [PATCH] Fix compiler warnings on MSYS2/Cygwin

/f/Projects/libpcap/fmtutils.c:114:20: warning: initialization of ג€˜char *ג€™ from ג€˜intג€™ makes pointer from integer without a cast [-Wint-conversion]
  114 |  char *errstring = strerror_r(errnum, strerror_buf, PCAP_ERRBUF_SIZE);
      |                    ^~~~~~~~~~

CMake executes the test for strerror_r with GNU_SOURCE defined,
but the actual application did not define it.
