In fact, there has been another report about rint on Windows not too
long ago. In that case, rint was present, but its implementation was not
standard-compliant. In your case, it seems it is completely missing. So
I'm changing the title of the mail in hope that somebody can shed some
light on what the support of rint with Microsoft compilers is. What is
happening with this function?

Anyway, back to your post. You may try to adapt the workaround I
suggested in the followup of the previous bug-report about rint:
