I looked at the warnings here and from what I can tell they've all been
fixed.

The regex.c one was fixed by correcting the type of 'ret'.

The emacsclient.c one was fixed by introducing tmpdir_storage and
passing it to confstr.

If you still see these warnings, please reply and we can reopen the bug.

thanks,
Tom

Hello!

When using

	Apple clang version 2.0 (tags/Apple/clang-139) (based on LLVM 2.9svn)
	Target: x86_64-apple-darwin10
	Thread model: posix

to compile GNU Emacs on Mac OS X 10.6.8 with intel Core i7 it warns about some statements:

emacs-24.0.50/lib-src/../src/regex.c:6603:15: warning: 
      comparison of unsigned enum expression >= 0 is always true [-Wtautological-compare]
      if (ret >= 0)
          ~~~ ^  ~

                            ^

The installed NS variant is a bit unstable. Maybe I just need to optimise the compiler switches in the near future!
