And for the top of tree, that's true.  For 2.95.2, it is not.  2.95.2
does support COFF generation.

This was an, err, negative interaction between GCC and the System V
linkers that Jason fixed in the top-of-tree a year or so ago.  I think
the patch was in the 2.95.3 backport set, but I'm not following 2.95.3.
It's definitely in the 2.95.2.pl1 (that's the patch that makes it "patch
level 1") binary kit available on Skunkware.

Aaaah, it's the "--enable-shared" that caused you grief.  This was
definitely naughty unless you specified --disable-multilib.
