+Subject: [PATCH] configure: Use macros earlier
+
+When building with slibtool using the rlibtool symlink the build will
+fail because it doesn't find the generated libtool. This is required so
+rlibtool can determine if its a shared or static build.
+
+This can be fixed easily by using LT_INIT earlier before AC_OUTPUT.
+Generally these should be used near the top of configure.ac.
