The log file at http://hydra.nixos.org/build/74591/log contains the lines:

  patching sources
  configuring
  fixing libtool script ./build-aux/ltmain.sh

What does "patching sources" mean? Where are the patches that are being applied?

What does "fixing libtool script" do? libunistring's embedded libtool script is
known to work fine on Cygwin 1.5.x.

Last not least, which version of cygwin are you using (show the result of
"uname -a")? 1.5.x or 1.7-beta?
