I found the problem, but it's not safe to fix it at this point.

Basically, the autotools on my system don't have important cygwin fixes,
so the generated ./configure script in the tarball has issues with
shared libraries on cygwin.

What you _can_ do is this: after unpacking the source on a cygwin box,
run these commands:

  aclocal -I /usr/local/share/aclocal
  autoheader
  libtoolize -c --automake
  automake --add-missing --copy --include-deps
  autoconf

Ignore the warnings from these commands, then just ./configure and make
as usual.
