--- Comment #2 from Paul Zimmermann <zimmerma+gcc at loria dot fr> ---
idem in extended precision:
Testing function tanh for exponent 0 [seed=8344].
rounding mode MPFR_RNDN:
wrong underflow flag for x=-1.0000000000000000@-4111
library gives -1.0000000000000000@-4111
mpfr gives -1.0000000000000000@-4111
underflow: mpfr 1, library 0
