+        Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
+        This bug was introduced by my 2013-02-25 change that simplified
+        data_start configuration.  Without this change, on GNU/Linux
+        an Emacs configured with --enable-profiling fails immediately
+        due to a profiler signal.
+        * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
+        with these flags.  On platforms where special flags are needed
+        when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
+        (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
+        (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
