Even if the project is a c++ project, the OmegaStartup is a very simple 
C function:

extern "C" void MemConfig(void);
extern "C" void mainCRTStartup(void);
using namespace std;

int main(int argc, char* argv[])
{
........
}

void OmegaStartup(void)
{
    MemConfig();
    mainCRTStartup();
}

I need MemConfing to be the first function called, even before the 
mainCRTStartup();
As you can see I know what I'm doing (this code always worked with MSC 
compiler and the option /entry: mainCRTStartup), what I actually don't 
know is how to do the same thing with MinGW.
I also noticed that in the object file the symbol for OmegaStartup has 
become Z12OmegaStartupv; despite on that the option -e Z12OmegaStartupv 
doesn't work too.
I'm sure that something escapes me, I've been struggling with this 
problem for 2 day...  any further help will be appreciate.
Thanks
