N_TXTADDR and N_DATADDR?

[Stephen the Greatest]

	I was recently trying to compile the GNU C++ (g++) and
	came up with some undefined functions (or macros?) in
	ld.c.  The two symbols:

		N_TXTADDR (x)
		N_DATADDR (x)
	
	are not defined in <a.out.h>; only N_TXTOFF(x) etc. are
	defined.  I am not sure why they put it in there, but
	anybody who can shed light on this?

	Also, I successfully compiled g++, c++, gnulib+,
	crt0+.o, crt1+.o, cpp+, but NOT ld+.  However, the
	compiler seems to run without ld+ and gives an a.out
	file.  Seems that the ld process was spawned instead
	of ld+ when I looked at it in ps.  The a.out gave me
	a core dump.
