It depends how the application handlers errors.  errno is usually not set
as specified.  The library attempts to set the IEEE exception masks to
report errors.  This sometimes fails because gcc doesn't fully support
IEEE.  ANSI applications can't use IEEE features anyway.  At best they
can hope that HUGE_VAL is a good value and is returned when specified
(it is), and that weird enough values are returned for range errors.
