Hi Andreas,

Coming back to myself. Doesn't matter if going to 128-bit long double or not. The LDBL_MIN/MAX/EPSILON definitions in float.h are wrong.

If you do a printf ("%Lf\n", LDBL_EPSILON); you run into a compiler warning:

warning: format '%Lf' expects type 'long double', but argument 2 has type 'double'

So to fix that I propose the appended patch.

Thanks, Andreas

P.S, making the compiler work with 128-bit long-double is

still possible.

I'm way out of my depth here. You probably want to speak to David Schulz (da@freebsd.org) - he's the floating point goto guy.

later,

Peter.
