--- Comment #3 from Paul Zimmermann <zimmerma+gcc at loria dot fr> ---
idem in extended precision:
Testing function atan for exponent 53 [seed=8344].
rounding mode MPFR_RNDU:
wrong underflow flag for x=4.0000000000000000@-4096
library gives 4.0000000000000000@-4096
mpfr gives 4.0000000000000000@-4096
underflow: mpfr 1, library 0
