Hi,

> ilmbase failed to build properly; the test suite failed.

ilmbase seems to be fairly new, so the question of whether the test suite 
ever worked on m68k is a bit moot.

If I parse the testsuite output right, it tries to do some rounding tests 
based on pathological bit patterns for floats? Maybe we should try to run 
that test suite on a 030 or 040 machine? I'm wondering whetther what we 
see here is a corner case in the 040 or 060 FPSP routines rather than a 
toolchain bug.

What kind of processor was that build run on?

That explains the slew of kdelibs related failures, thanks.

I'll have a look at it.

Yay! That should take the guesswork out of some build fails (and may even 
prove useful in ordering the builds more intelligently!).

Thanks for this, Wouter!
