calling D2 routines from C routines on linux

[Andrej Mitrovic]

See if this works for you:

import core.runtime;

void myMainFunc()
{
}

extern (C)
int initializeDee()
{
    int result;
    void exceptionHandler(Throwable e) { throw e; }

    try
    {
        Runtime.initialize(&exceptionHandler);
        result = myMainFunc();
        Runtime.terminate(&exceptionHandler);
    }
    catch (Throwable o)
    {
        result = 0;
    }
    return result;
}

This is similar to how it's done for Windows GUI applications, where
we have to manually run the initialize function in druntime (unless
it's hidden by some GUI framework).
