=head2 Compilation improvements
-XXX
+Fix CCINCDIR and CCLIBDIR for mingw64 cross compiler to correctly be under
+$(CCHOME)\mingw\include and \lib rather than immediately below $(CCHOME).
+
+This means the 'incpath', 'libpth', 'ldflags', 'lddlflags' and
+'ldflags_nolargefiles' values in Config.pm and Config_heavy.pl are now
+set correctly (23ae7f).
