 ...now I'm back to the original error John had, just in tininterpolator.
 So interpolator is doing something right so that isnan works.  Or
 tininterpolator is including another header that includes <cmath> (the
 trail was too tangled for me to follow).

 As a test, I changed isnan() in tininterpolator to std::isnan() and it
 compiled.  Doing the same for interpolator breaks with:

 {{{error: expected unqualified-id before '(' token}}}

 So there seems to be some sort of namespace issue in tininterpolator, or
 <cmath> is included somewhere.
