I see the problem. (And the guess in my previous email was wrong.)
The workaround above was intended to solve a problem on Cygwin whenever
the emacs build depended on Glib. When I provided that workaround, I
thought this only happened in a GTK build. But I see now that there are
other things that can cause emacs to depend on Glib, even in a Lucid
build. This happens in both the trunk and the emacs-24 branch.
The following patch fixes it:

setenv ("G_SLICE", "always-malloc", 1);
#endif
Stefan, is it OK to apply this to the emacs-24 branch? The bug is not a
regression, but I think the patch is clearly safe. And it affects only
the Cygwin build.
