+- update to 1.7:
+  * Multiple start functions are allowed
+  * New option --target=FUNCTION
+  * New output format: dot
+  The '-f dot' (or '--format=dot') option instructs cflow to output
+  graph as a description in DOT language, suitable as input to graphviz
+  programs.
+  * Bugfixes:
+  ** CVE-2019-16165
+  ** CVE-2019-16166
+  ** Fix parsing of K&R style function declarations
+  ** Improve parsing of typecasts
+  ** Fix recursive call detection
