+// Like the compiler, the static analyzer treats some functions differently if
+// they come from a system header -- for example, it is assumed that system
+// functions do not arbitrarily free() their parameters, and that some bugs
+// found in system headers cannot be fixed by the user and should be
+// suppressed.
