You mean, Emacs 24.3 Release Candidate 2, right?

This should go to bug-gnu-emacs@gnu.org or emacs-devel@gnu.org.  The
release manager of Emacs must be alerted to any problems in release
candidates ASAP.

Why do you run autogen.sh when building from a release tarball?  It's
not needed, and you are running the risk of getting a bad configure
script and Makefile's.

Hard to tell.  It looks like some strange temporary object file
(/tmp/ccntBfBN.o) causes multiple definitions of inline functions
defined on standard headers.  Add -v to the link command line and
examine the output produced by GCC when linking, it might tell you
what is wrong.

If you cannot fix this or convince yourself it's a pilot error,
_please_ report it to one of the lists mentioned above ASAP.
