+ * -DEXTERNAL_COMMANDS=0  to disable the running of all external commands.
+ * -DFILEXFER=0  disable filexfer.
+ *
+ * -DHARDWIRE_PASSWD=...      hardwired passwords, quoting necessary.
+ * -DHARDWIRE_VIEWPASSWD=...
+ * -DNOPW=1                   make -nopw the default (skip warning)
+ * -DPASSWD_REQUIRED=1        exit unless a password is supplied.
+ * -DPASSWD_UNLESS_NOPW=1     exit unless a password is supplied and no -nopw.
+ *
+ * -DWIREFRAME=0  to have -nowireframe as the default.

+ * -DBOLDLY_CLOSE_DISPLAY=0  to not close X DISPLAY under -rawfb.
+ * -DSMALL_FOOTPRINT=1  for smaller binary size (no help, no gui, etc) 
+ *                      use 2 or 3 for even smaller footprint.
+ * -DNOGUI  do not include the gui tkx11vnc.
