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).
