There's no need to compile the code as C++: compile entities.c as -std=c99 and link the object file with your C++ code, eg if you have the follwing example program foo.cpp

#include <iostream>

extern "C" size_t decode_html_entities_utf8(char *dest, const char *src);

int main()
{
    char line[100];
    std::cout << "Enter encoded line: ";
    std::cin.getline(line, sizeof line);
    decode_html_entities_utf8(line, 0);
    std::cout << line;
    return 0;
}

use

g++ -o foo foo.cpp entities.o
