I just went through a painful experience that might be related.  I was
putting together some function libraries that were originally written
for Lattice C, and had huge number of errors on all of the functions
written in assembler.  After a lot of trouble, I found that there are
several rules to be followed when integrating assembler:

	1 - All PUBLIC labels (function names) must be preceeded by
	    an underscore character.
	2 - The code segment must be named '_TEXT' (at least in the
	    small model, which is all I used. See the manual for segment
	    names for larger models.)
	3 - The 'class' must be type 'CODE'.  My experience with this
	    is also limited to the small memory model.

I hope this is helpful.
