Hmm, you tripped over a landmine :-(.  In the past many of GDB's 
testcases were incorrectly XFAILed (as a way of hiding design flaws that 
were thought to be unfixable / or the individual had no intention of 
fixing ...).   XFAIL only applies to problems eXternal to GDB (OS bugs, 
...) which these are not.

I've removed the offending XFAIL junk.
