localtime_r support on MinGW

Question

I'm working on a Win32 multithread C++ project and I would like to use one of the localtime_* thread-safe alternatives to localtime().

Unfortunately I have to use MinGW compiler, and localtime_s cannot be used outside Microsoft stuff.

The problem is that neither localtime_r is working: the related code snippet is

#include <ctime>

...

string getCurrentTime()
{
    time_t t;
    time(&t);
    struct tm timeinfo;
    //localtime_s(&timeinfo, &t);
    localtime_r(&t, &timeinfo);

    char buf[128]; 
    strftime(buf, 128, "%d-%m-%Y %X", &timeinfo);

    return string(buf);
}

...

This is the compiler output:

error: 'localtime_r' was not declared in this scope

Does MinGW support localtime_r ?

If not, does exist a thread-safe alternative? (excluding boost/QT/etc that I can't use).

No.

mingw will use the native localtime function on windows, which is thread safe. (But it's not reentrant, so watch out for that).
