I get notation like "1e-09".  I think (but am not sure) that there
were some changes in mingw's stdio.h that got rid of the errors about

I don't have any plans to do that, mainly for fear that I would find
some problems and be sucked down the rabbit hole of trying to solve
them!  Hoping someone else more knowledgeable will take the plunge :)
