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)
~~~ ^ ~
emacs-24.0.50/lib-src/../src/regex.c:6619:14: warning:
comparison of unsigned enum expression >= 0 is always true
[-Wtautological-compare]
return ret >= 0 ? REG_NOERROR : REG_NOMATCH;
~~~ ^ ~
emacs-24.0.50/lib-src/emacsclient.c:1269:52: warning:
passing 'const char *' to parameter of type 'char *' discards qualifiers
confstr (_CS_DARWIN_USER_TEMP_DIR, tmpdir, n);
^~~~~~

/usr/include/unistd.h:423:28: note: passing argument to parameter here
size_t confstr(int, char *, size_t) __DARWIN_ALIAS(confstr);
^
The installed NS variant is a bit unstable. Maybe I just need to optimise the
compiler switches in the near future!

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
