execution, "a programmer can safely assume default modes (or be unaware of
them)" (7.6/2, footnote 161 of the August 3, 1998 draft of C99). Reportedly,
on Windows there are printer drivers that switch on exceptions. To avoid
problems, the SAL_MATH_FPEXCEPTIONS_OFF macro can be used to explicitly
switch off exceptions (on Windows).
