Hi Peter,

can somebody explain why we have these defines in sys/powerpc/include/float.h ?

Have a look at

http://svn.freebsd.org/viewvc/base?view=revision&revision=132421

Hm, meanwhile OS-X has 128-bit long double...

Basically, the ABI was switched from 128 bit long doubles to 64. Not exactly SVR4 compliant but then no-one else is.

And there is no need to go back to 128-bit? No benefit? What would have to be done? Libc? I know the compiler issue. Would this break too much?

Thanks, Andreas
