+Q16.  When I trying building Valgrind, 'make' dies partway with an
+      assertion failure, something like this: make: expand.c:489:
+      
+        allocated_variable_append: Assertion 
+        `current_variable_set_list->next != 0' failed.
+      
+A16.  It's probably a bug in 'make'.  Some, but not all, instances of
+      version 3.79.1 have this bug, see 
+      www.mail-archive.com/bug-make@gnu.org/msg01658.html.  Try upgrading to a
+      more recent version of 'make'.
