Concerns about .../src/lib/libc/gen/glob.c in 8-CURRENT

Hi again all,
      Not sure who yanked up the warnings or if gcc is in a particularly bad
mood but it appears that compiling this source file is now failing on
8-CURRENT for me with the following message:

cc -fpic -DPIC -O3 -pipe -fno-strict-aliasing -march=prescott

/devel/ncvs/src/lib/libc/gen/glob.c:242: warning: initialization discards
qualifiers from pointer target type
*** Error code 1

      I didn't remember what the error was but looked it up and it appears
that there was some concern about casting and modify the reference that a
const pointer was pointing to.
      I looked over the source and although I was concerned about the code
in globexp2 (in particular the reassigning of const pointers and
incrementing going on), I didn't see anything wrong in globexp1. I could
have totally missed something non-obvious though...
Thanks,
-Garrett
