Please note that I implemented this in a way that only the POWER() function is
affected. Uses of the libc/C99 pow() function in other formulas is unaffected.

What I did was actually add a powr() function to SAL. powr() is described in
IEEE 754-2008 but has not been implemented in any libc, that I know of.
