Carlos O'Donell 3c47c83a97 Ensure isinff, isinfl, isnanf, and isnanl are defined (Bug 19439)
In ICO C++11 mode ensure that isinff, isinfl, isnanf, and isnanl
are defined.  These functions were accidentally removed from the
header as part of commit d9b965fa56350d6eea9f7f438a0714c7ffbb183f,
but being GNU extensions, they should have been left in place.
