Make IEEE754 check more robust

This change should prevent compilers from
optimizing away the structure used for checking
strings in the binary by also using it to produce
a return values. There are now also clearer
warnings, and if IEEE754 cannot be detected we
fall by to using the OS versions of erf/erfc()
in double precision. Fixes compiles on Power7.
