No, because it wouldn't work.  This has nothing to do with static vs.
dynamic.  While the format of a .a file may be similar that doesn't
equate to object file interoperability.  Cygwin's nm and ar commands
could theoretically read archives from a number of other operating
systems.  That doesn't mean that the objects that are in the archive
could be linked in.
