      Thanks for the fix! This of course suits me. I did further modify
it in the hope (apparently well-founded) that it would also fix the CW 9
on Intel problem.

      The remaining outstanding problems with quaternions, octonions and
special functions all revolve around "long double" problems which I
believe are due to the libstdc++ of these platforms which seem to have
some deficiency w.r.t. 64 bits computing (the Beman/Win32/gcc result is
odd, though, and will need further investigation). Jonathan Wakely is
investigating the matter and in the end, if necessary, I can (but would
rather not) disable the test for "long double".

      A few scattered problems remain as well, COMSOFT apparently fails
to define the "float atan(float)" signature (and provides useless output
for the quaternion and special functions tests), the FFT-icc 8 results
seem irrelevant and SunPro 5 gets tripped by "for_each" (which seems to
pulled in somehow...). At worst these can be marked as expected failures.



P.S.: sorry for the rather asinch replies I make to various threads, but
things are a bit hectic lately, and I have not even managed to read all
I would like to here; should be smoother next month, and definitely
better in August :-) (not to mention July, where I'll be almost one
month off-line, on vacation :-)) ).
