Re: Keeping clean build and test status

No, I don't.  There are various possible reasons those could be seen by 
some people but not others: multi-arch means different implementations of 
libm functions may be used depending on what features your processor has, 
and some x87 functions may not produce exactly the same results on all 
implementations.  Apart from those, the way GCC handles excess precision 
by default means the results on 32-bit x86 (and certain m68k processors) 
could also depend on the exact compiler version and options used to 
compile the library (similarly, results may be unpredictable in nondefault 
rounding modes if the code is built without -frounding-math).
