+LD_PRELOAD by itself only works with Cygwin builtin functions, but
+textdomain() and friends come from libintl.  In order to override
+those functions, we have to "replace" cygintl-?.dll since functions are
+bound to a DLL name at link time.  Our replacement will be used since
+it is loaded first by LD_PRELOAD.
+
+But as we are making this *the* libintl, we need to provide 
+pass-throughs for the other functions which we're not overriding,
+otherwise Locale::gettext won't load (not to mention the program
+that we're trying to help2man).
