+     dnl libtool insists upon adding -nostdlib and a list of objects/libs to link against.
+     dnl That breaks our ability to build dll's with static libgcc/libstdc++/libssp. Override
+     dnl its command here, with the predeps/postdeps removed, and -static inserted. Postdeps are
+     dnl also overridden to prevent their insertion later.
+     dnl This should only affect dll's.
