But i have the 68882 fpu installed, is'nt this switch useful at all
(apart for the kernel)?

Yes, same binutils 2.21 since Vincent released them (in february if i
remember well).
I've checked the cvs releases with the -D switch from  may 30 to  june
04 and the make error appear only after that release. So something is
changed in the sources. I'm just curious to know why the 020-60 switch
was working before and not now.

And now that i know that, i'm back to standard kernel :)
