This test previously passed, now it fails.
A patch in the revision range (last_known_working:first_known_failing)

exposed or caused this regression.  Since then it fails as follows:

FAIL: gcc.dg/setjmp-1.c spurious clobbered warning (test for bogus messages,
line 16)

Author of suspect patch in revision range CC:ed.

Preprocessed setjmp-1.i attached; the regression might be related to the actual
target-specific setjmp implementation (though simple and non-surprising,
non-inline).
