* -DXINERAMA=0 to have -noxinerama on by default.
* -DADDKEYSYMS=0 to have -noadd_keysyms the default.
*
* -DREMOTE_DEFAULT=0 to disable remote-control on by default (-yesremote).
* -DREMOTE_CONTROL=0 to disable remote-control mechanism completely.
* -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)
* -DUSEPW=1 make -usepw the default
* -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.
* -DWIREFRAME_COPYRECT=0 to have -nowirecopyrect as the default.
* -DWIREFRAME_PARMS=... set default -wirecopyrect parameters.
* -DSCROLL_COPYRECT=0 to have -noscrollcopyrect as the default.

* -DXDAMAGE=0 to have -noxdamage as the default.
* -DSKIPDUPS=0 to have -noskip_dups as the default or vice versa.
*
* -DPOINTER_MODE_DEFAULT={0,1,2,3,4} set default -pointer_mode.
* -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.
* -DSKIP_HELP=1 smaller.
* -DSKIP_XKB=1 a little smaller.
* -DSKIP_8to24=1 a little smaller.
* -DPOLL_8TO24_DELAY=N
* -DDEBUG_XEVENTS=1 enable printout for X events.
*
* Set these in CPPFLAGS before running configure. E.g.:
