This used to be a problem with the gtk build, for which the following 
workaround was put into emacs.c long ago:

#if defined (USE_GTK) && defined (G_SLICE_ALWAYS_MALLOC)
   /* This is used by the Cygwin build.  */
   setenv ("G_SLICE", "always-malloc", 1);
#endif

My guess is that Cygwin doesn't support building with x-toolkit=athena 
(or else you don't have the appropriate devel packages installed).  The 
build probably then reverted to the default gtk, but USE_GTK wasn't 
defined, so the code above didn't get invoked.  I'm guessing, because I 
can't tell anything from the config.log fragment that you attached, and 
I don't have time right now to dig into the code or to try a build with 
x-toolkit=athena myself.
