Hi Max,

Like I said, the Makefile is crappy. The point is not in the Makefile - if 
it were OK, ld wouldn't give any errors at all ;)

The point is that ld is segfaulting. I don't know whether it's specific to 
Cygwin, which is why I posted here first.

As nobody has been able to point me to a cause inside ld (yet), I'll do 
some the necessary digging myself when I have the time.
