Well, since I am currently writing some mathematical stuff, can someone 
be more specific about this issue? I mean:

* Does it mean that "double" precision roundoff is correct on BSD, 
whereas "long double" is not — and vice-versa on Linux?

* What shall be done (in the user code) in order to ensure that results 
computed on NetBSD and Linux are consistent (regardless of GCC initial 
configuration)?

Thanks,
