For anyone who, like me, supports IDL installations still
using 4.0, there is no way to have a single source version
of your IDL application which uses the new 5.0 POLY_FIT,
since the 4.0 version has no /DOUBLE keyword.
Until the whole world uses IDL 5.0, the solution must be to
use the 4.0 POLY_FIT and distribute it with your source code,
so the 5.0 site will have it. There is no accuracy penalty, and
I can't perceive any speed differences.
That is the only way to avoid having version-
dependent code. (I don't find anything in the Index under
"version" that would let me determine the IDL engine's
version, anyway, even if I were interested in doing that
kind of workaround...)
