Re: [Sbcl-devel] glitches in compile of 1.0.34 on ppc OS X 10.5.8, and floor/ceiling/round optimization

[JTK <je...@gm...>]

Thanks!

So in float-tran.lisp I commented out the macrolet containing
a deftransform for truncate, and I don't get the compilation notes any more.

Is this safe?  I don't really understand what happens in the absence of
a deftransform.
