Hmm... this is powerpc64.

This just explains why there's no extended precision on Linux/ppc. You can use long double, but if you want to be portable enough, your program must not require extended precision. -- Vincent Lef�vre <[EMAIL PROTECTED]> - Web: <http://www.vinc17.org/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.org/blog/> Work: CR INRIA - computer arithmetic / SPACES project at LORIA
