math_errhandling is specified by ISO C, starting with the 1999 edition
of the standard.
The value of math_errhandling is determined by the implementation, not
by the application. "The value of math_errhandling is constant for the
duration of the program." (A compiler could provide an option to set
the value; I don't know whether any do so.)
