+ *
+ * We, however, will include it if we know we have an MSVC version that has
+ * it; this means that we may define the INTn_MAX and UINTn_MAX values in
+ * scanner.c, and then include <stdint.h>, which may define them differently
+ * (same value, but different string of characters), causing compiler warnings.
+ *
+ * If we include it here, and they're defined, that'll prevent scanner.c
+ * from defining them.  So we include <pcap/pcap-inttypes.h>, to get
+ * <inttypes.h> if we have it.
