I don't think so. Both BP (your paragon) and GPC don't. The standard, if you care, does not seem to explicitly mention this case, but since it refers to the usual mathematical rules, I understand that it doesn't allow it, either.
If you want access to these special values, you might rather want to supply them as predefined constants (like MinReal, MaxReal and EpsReal) -- though there may arise problems on non-IEEE FP systems (if you support any) which may not even know those values ...
