+vncmkdepend
+===========
+
+This code is taken from the X11R6 makedepend sources.  All I have done is:
+
+ * Remove all predefined symbols, include directories and other
+   platform-specific behaviour.  Its behaviour should be the same on all
+   platforms.  All symbols and include directories must be explicitly given on
+   the command line with -D and -I flags.
+ * Fix processing of numbers in #if expressions.
+ * Fix processing of -D flag.
+ * Fix C++ comment handling.
+ * Improve #error warnings.
+ * Change the output so that processing <name>.<suffix> produces <name>.d
