NOOOOOOOOOOO!!!!!!!!

DO NOT rm -f /usr/lib/*.la!!!!!!!  There are more .la files in there 
than simply the ones from gcc; it's the gcc-supplied .la files that are 
causing the problem, not the other ones.

The reason the gcc-supplied .la files are causing a problem is because 
they specify only a static lib, and not a DLL.  (Of course, since gcc 
doesn't supply the runtime libs in DLL form, the .la files can't very 
well specify DLLs.)

Upcoming libtool works around this problem with gcc's .la files. 
Upgrade to the experimental libtool-devel package here:
http://www.neuro.gatech.edu/users/cwilson/cygutils/testing/

I'm trying to get these patches accepted into libtool CVS
http://mail.gnu.org/pipermail/libtool-patches/2002-November/002236.html

Since cgf has brought this issue out, I'll be putting the experimental 
libtool-devel on sources as a 'test' release soon.  (Were you trying to 
prod me, Chris?)
