Hi,

Sorry this took so long.  Has anyone tried current with a full up
040 recently?  Does it work?

Good news and bad news. 

The good news is that the patch looks almost correct, but,
the changes to the libm makefile didn't get copied.  The changes 
are below.

The bad news is that while the 2.99.10 kernel seems to work fine,
install kernel does not work for me as well.

I'm doing a clean build just in case the install kernel was using 
libm.

cheers

bruce
