But it DIDN'T query me when I redefined a global function. My file
redefined ARRAY-DIMENSIONS and when I loaded the file into my new
package SCHEME without shadowing it, it redefined the global function
without querying me....
Hmm, it's supposed to. However, I noticed that nothing prevents the
variable INHIBIT-FDEFINE-WARNINGS from being screwed over by a warm boot.
This will be fixed in the next system; in the meantime you might want
to make sure this is NIL before loading something that might redefine
things. It might even be that there is a dumped-out, distributed band
with this variable accidentally set to T in it for some reason.
