Использую libstdc++4.4-devel-4.4.0-alt3. Здесь эти определения
присутствуют только если не определен символ препроцессора
__CORRECT_ISO_CPP_STRING_H_PROTO, который, вроде бы, должен
определяться в <string.h> из glibc-devel-2.10.1-alt2 на 37-ой
строке. Я успешно скомпилировал такое вот:
$ cat a.cpp
#include <cstring>
const char* test = "Test";
const char* accept = "s";
int main()
{
return std::strpbrk(test, accept) - test;
}
Полученный бинарник действительно возвращает код 2.
Может, у Вас какой-то string.h подсоввывается неправильный? Что за
пакет?
