first of all, you probably don't want -march=1.0 .... try 1.1
also there are some floating point issues on hppa-linux right now. willy
mentioned that the 'long double' type is broken (gcc and glibc don't
agree on its size) but i don't know if that's the problem in atlas.
python2 also has a sqrt on floating point number problem, but i don't
know if it's related to this or not.
if you can provide a simple test case that is failing, it'll help us
track down the problem.
