+
+  Byte compilation writes errors and warnings into the buffer
+@samp{*Compile-Log*}.  The messages include file names and line
+numbers that identify the location of the problem.  The usual Emacs
+commands for operating on compiler diagnostics work properly on
+these messages.
+
+  However, the warnings about functions that were used but not
+defined are always ``located'' at the end of the file, so these
+commands won't find the places they are really used.  To do that,
+you must search for the function names.
