I'm running g++-3.0 here without much problems.  It turned out libstdc++
was not installed correctly and the static constructors are not called on
main.  Here's what I added to my main:

// Ugly, G++ needs to be installed correctly.
void
ctors(void)
{
	typedef void (*func_ptr)(void);
	extern func_ptr ___CTOR_LIST__[];

	for (int i = 0; i != (int)___CTOR_LIST__[0]; i++)
		___CTOR_LIST__[i + 1]();
}

int
main(int argc, char **argv)
{

	ctors();
	...

}

The usual practice is to use a crt0 module that calls them.
This should be in the C++ system library.
