Getting the sources ready for the next Solaris developer studio toolchain. Some additional warnings were found in the debug build.
Issue: https://bugs.openjdk.java.net/browse/JDK-8202319 Webrev: http://cr.openjdk.java.net/~gadams/8202319/webrev.00/ This update conditionally disables some new error checks, if the new toolchain is used.
