+Subject: [PATCH] examples/userloc_formatter.c: drop usage of sd_debug()
+
+With recent compilers, log4c-localtime fails to build with:
+
+userloc_formatter.c: In function 'userloc_format':
+userloc_formatter.c:30:5: error: implicit declaration of function 'sd_debug' [-Wimplicit-function-declaration]
+   30 |     sd_debug("Formatter s13_userloc checking location info for userdata %X",a_event->evt_loc->loc_data);
+      |     ^~~~~~~~
+make[4]: *** [Makefile:519: userloc_formatter.lo] Error 1
+
+This function seems to be an internal function of the log4c-localtime
+library, and is not used by any other example application. Since it's
+only used to print some debugging information, we simply get rid of
+the problematic code.
