Конфликт pcap.h и stdio.h

Заранее оговорю, что я только начинаю изучать c++. Спасибо за понимание. Использую QT на Windows, использую pcap, но при включении библиотеки(#include <pcap.h>), выдает ошибки(приведены ниже, заранее извиняюсь, что в такой форме..) Как я понял, stdio.h и pcap-stdinc.h конфликтуют в методах _snprintf и _vsnprintf, т.к. pcap подключает сам библиотеку stdio.

Часть файла pcap-stdinc.h

#if _MSC_VER < 1500
#define snprintf _snprintf
#define vsnprintf _vsnprintf
#define strdup _strdup
#endif
