Starting today, if I configure with Xcode 4 on OS X 10.9, I can no longer build
jdk9/dev/hotspot (changeset b329ff11a78c).
make dist-clean
sh configure
--with-tools-dir=/Applications/Xcode4.app/Contents/Developer/usr/bin
--with-toolchain-type=gcc --with-boot-jdk=$JAVA8_HOME
make images
...

/Users/dan/Dev/jdk/jdk9/hotspot/src/share/vm/trace/traceStream.hpp:69: warning:
format ‘%lld’ expects type ‘long long int’, but argument 4 has type ‘s8’
Fortunately, I can now cleanly build with Xcode 5:
make dist-clean
sh configure --with-boot-jdk=$JAVA8_HOME
make images
However, I don't know if it is intentional that Xcode 4 support is being
dropped.
