I am trying to find regressions in a certain compiler config, and it fails math_info test as soon as it tries to evaluate the signalling NaN values - as it duly generates an unhandled signal and terminates.

Borland eh? Math_info relies on numeric_limits to return the correct answers to it's queries: with Borland it reports that it *does* have a quiet NaN, but as soon as you *call* numeric_limits<>::quiet_NaN() the program aborts with an unhandled hardware exception! :-( Maybe we should add some #ifdef's in there so the program does at least run to completion?
