[cmucl-imp] Re: Static array support

[Lynn Quam]

I have checked out the lastest CVS sources, containing 
make-static-array, and have built for x86-linux.  I will run some tests 
using FREEDIUS, which makes extensive uses of foreign-vectors.  I have 
examined the sources and the implementation looks like it should work well.
