Roberto Bagnara's cursory examination of those results was that these were flaws in the testsuite itself and not real errors. I don't seem to see them in ppl cvs.

Dear Jack,

I have checked more carefully and found that the testsuite is OK. My guess is that PPL 0.9 does not use the -frounding-math GCC option for compilation. This was fixed in:

* configure.ac (1.283): With GCC, use -frounding-math to disable transformations and optimizations that assume default floating point rounding behavior.

I can only repeat my invitation to base any new development on (prereleases of) PPL 0.10. Cheers,

Roberto
