bug? ratinterpol generates 0^0 / pattern matching

Hello,


The origin of the slowness is the symbolic solution of a linear system 
in linsolve_by_lu, where the matrix of coefficients has a lot of 
expressions depending on b3.

I have commited a patch for the 0^0 bug:

http://maxima.cvs.sourceforge.net/viewvc/maxima/maxima/share/numeric/interpol.mac

This change makes the algorithm faster, but your original problem is 
still a hard one.

Thanks for your report
... and sorry for the bug.
