You're right, the standard only defines the const versions, though I
believe this is a (minor) flaw in C++.
I think the original reasoning was to allow a polar implementation,
which would however be insane for a multitude of other reasons.
Such an implementation would break Octave anyway.

I added non-GNU code to str2double.
