Looks like some bug in GetModuleFileName() was fixed and this broke
CommandLineToArgvW

Test: (builds with mingw)
*************************************
#include <windows.h>
#include <stdio.h>

int main()
{
    int i, numargs;
    for (i = 0; i < numargs; i++)
    {
        printf("argv[%d]: %S\n", i, CommandLineToArgvW(L"", &numargs)[i]);
    }
    return 0;
}
*************************************
result:
*************************************
