I meant "system misbehaviour".

IMO, XFAIL means "unsupported system feature" or "system misbehaviour" 
in my previous reply, but ...

... it doesn't mean we should use XFAIL for *every* "unsupported system 
feature", IMO.  XFAIL can be used for "unsupported system feature" in 
gdb test, but XFAIL (nor PASS) can not be used in checking the feature 
of system, because checking itself is not a test.  I'd like to call them 
(proc skip_XXX and proc support_XXX in lib/gdb.exp) 'test configuration 
checking' which determines the set of tests to run according to the 
configuration of GDB and other factors.  They should not contribute 
PASS/XFAIL/FAIL/... to test result, because they are not tests.
