I am trying to port gnu (18.47 I believe) to an opus card.
An opus card is a card with a clipper chip set running sys V.3 
that fits into an AT.  Well I am having a few problems and
was wondering if someone has already done it for me?  If not
I have two questions.

1) this thing wants to link with '__start'.  I don't know
how to deal with this.  It should be able to link with
'start' in crt0 shouldn't it?  I was able to avoid the
problem by defining 'CANNOT_UNEXEC' but this shouldn't be
necessary.

2) My compiler passes the first two arguments to a function call
in registers.  Well it is sort of hard to take the address of
a register so I defined "NO_ARG2_ADDRESS" and put a little hack
to fix it everywhere that the compiler complained. Ex.

before

	a = &arg1;

after
#ifdef NO_ARG2_ADDRESS
	{
		int cp_arg1=arg1;

		a = &cp_arg1;
	}
#elseif
	a = &arg1;
#endif

Anybody not like this for any GOOD reason?


thankyou
