That's not how libtool works on cygwin -- remember that libtool only
want's you to see (and thus link against) the libfoo.la file.  Behind
the scenes it maintains a static library, libfoo.a, and a dynamic
library, libfoo-<release>.dll.  When you link against libfoo.la and
libtool decides you want dynamic linkage, it will generate an import
library from libfoo-<release>.dll *on the fly*.

I have no objections to using cyg instead of lib as the default prefix
for libtool built dlls on cygwin, but installing an import library
would be a step backwards IMHO.  If you do want to install it (for
people who don't like libtool perhaps), I would suggest naming it
cygfoo.dll.a.

Cheers,
	Gary.
