Comment (by charris):

 Microsoft compilers treat the long double type as a double, at least up to
 VC++8.0

 "So the two types are distinguishable, though both types are currently
 mapped to the same double precision format; that is, sizeof(d) ==
 sizeof(ld).  Much to my chagrin, VC++ still doesn’t have extended
 precision long doubles (yes, even in version 8.0!).  This has been a point
 of longstanding criticism of our product.  For years processors have
 provided the capability of extended precision, yet VC only provides
 support for double precision."

 So this looks like a compiler problem. I think this ticket should be
 closed as invalid. Maybe another compiler should be used for the windows'
 platform? I don't know what is going on with OSX, I think it uses the gcc
 compiler, but I suspect there it is a compiler problem there also.

 Heads up on another problem coming: MS Vista limits binaries compiled with
 "foreign" compilers to 32 meg of memory. It is said this will be fixed by
 SP1.
