+- Issue #13590: Improve support for OS X Xcode 4:
+ * Try to avoid building Python or extension modules with problematic
+ llvm-gcc compiler.
+ * Since Xcode 4 removes ppc support, extension module builds now
+ check for ppc compiler support and automatically remove ppc and
+ ppc64 archs when not available.
+ * Since Xcode 4 no longer install SDKs in default locations,
+ extension module builds now revert to using installed headers
+ and libs if the SDK used to build the interpreter is not
+ available.
+ * Update ./configure to use better defaults for universal builds;
+ in particular, --enable-universalsdk=yes uses the Xcode default
+ SDK and --with-universal-archs now defaults to "intel" if ppc
+ not available.
