+	* configure.ac, src/generic/util/exception.cc:
+
+	  Make the dynamic generation of backtraces a configure-time
+	  option; in order for them to be useful, a full symbol table
+	  needs to be shipped with the program, and in the case of
+	  aptitude, this DOUBLES the executable size.
+
 	* configure.ac:
 
 	  Put libraries detected by configure into LIBS, not LDFLAGS.
