   OK, I have it generating a dll file now.  I still need to test if 
ObjC *works* with the DLL, but I thought I'd run this diff out to see 
if anyone spots any problems this might cause (I can't imagine what, 
but...)

   This patch is against the gcc-3.2.1-20021201-3 MinGW tarball, but I 
wouldn't be surprised if it worked on the head too :)

   This turns off the setting of 'allow_undefined_flag=unsupported' 
since the ObjC DLL doesn't *have* any undefined symbols, so there is no 
need to allow them!  Also, this changes the shell syntax to not bork 
the defs file -- It could well be that /bin/sh is busted on Mac OS X 
(from whence I'm cross compiling), but it is now bash:

% /bin/sh --version
GNU bash, version 2.05a.0(1)-release (powerpc-apple-darwin6.0)
Copyright 2001 Free Software Foundation, Inc.

   ... so I'd expect it to be reasonably close to what other folks have.

   I'll let you all know if I can get the DLL actually working in a bit. 
:)
