The functional change seems fine to restore support for SIGINFO. I'm 
still a bit perplexed as to when exactly it got removed. :)

I don't understand how the new test can pass on any platform except 
BSD/OSX ?

Please update the copyright year in 
test/jdk/sun/misc/SunMiscSignalTest.java.

Thanks,
David
