But why symlinks at all?  The files named "lib(u)chicken-0.dll.a" just
aren't what *anyone* uses in Cygwin or otherwise, so there is no point
in keeping them.  Do the rename (i.e. copy+delete) to arrange for the
file to have the correct name.

FWIU, the next version of CMake will do the Right Thing on Cygwin:
cygfoo-0.dll in $PREFIX/bin, libfoo.dll.a in $PREFIX/lib.  That's what
we should emulate.

*shrug*

I'm not a big fan of "sinking feelings" without evidence.

Okay, here's what "darcs diff" says:

This approach is very simple, no more of a kludge than what you have,
and *works*, *works*, *works*.
