It would be desirable to add an architecture-independent testcase that, if 
FE_NOMASK_ENV is defined and feupdateenv (FE_NOMASK_ENV) succeeds, the 
exceptions are then enabled as indicated by fegetexcept (or by getting 
SIGFPE, as test-fenv.c tests various cases, but a test using fegetexcept 
is simpler to write).  (It's best for this to be a new test rather than 
adding to the things in test-fenv.c.)

	[BZ #16918]

is how we indicate in a ChangeLog entry that a bug is being fixed (or 
partly fixed).
