These errors are difficult to nail down, but what you've done is reference
a symbol as an absolute value which is not defined at assembly time.  An
example might be:
        mov     r0,IM_VAL

The way I'd find this one would be to do a binary search (ugly, but effective)
within the macro.  Just use #if 0/#endif to take away parts of the code until
you've isolated the lines in question.  N.B. there may be other ways, but this
has always worked for me.
