Yes, they're external symbols/labels; yasm treats them as labels in an unknown
segment.  Is this code in the .text segment as well?  If it is, it should work
on a recent snapshot of yasm--support for sym-sym was added after the 0.6.2
release (yes, I really need to get a new release out!).  What version are you
using?
