--- Comment #31 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Using openlibm should work now.

I'm inclined to close this as WONTFIX, since the problem is in djgpp.

I don't think it's worth doing more work here. If there is interest in maki=
ng
<cmath> work better for djgpp then improving djgpp's <math.h> would be the
place to start.=
