That's what I thought, too, until I got bit.  Check the cygwin(-apps?) 
ml archives during spring/summer 2000.  At the time, the symptoms seemed 
like a smoking gun: link by ordinal == link ONLY by ordinal.  OTOH, 
binutils on cygwin was royally broken at the time, DJ was transitioning 
away from cygwin, Mumit had been gone for half a year or more, and bit 
rot was setting in.

Perhaps the problems that burned me then were due to broken 
binutils/maintainerless cygwin-gcc, and it wasn't the smoking gun I 
thought it was.

OTOH, if you've linked by ordinal, and then you strip symbols -- are the 
names of the imports still retained?
