To be correct: ifdef returns false for
forward references and therefore jmp is assembled
by AVRASM2.

I agree, but...

... how do solve the problem:
jmp_ A:
nop
nop
A:
The final address of A depends on the size
of jmp_ expansion, that may be 1 word
or 2 words. Size of the jmp_ expansion
depends on how for A is. Isn't that
a circular reference?
