[XBoard-devel] compiling issues

[Eric Mullins]

I compiled xboard, but got problems in the Xaw3d widget set.  It 
complained as follows:
   configure: WARNING: X11/Xaw3d/Dialog.h: present but cannot be compiled
   configure: WARNING: X11/Xaw3d/Dialog.h:     check for missing 
prerequisite headers?
   configure: WARNING: X11/Xaw3d/Dialog.h: see the Autoconf documentation
   configure: WARNING: X11/Xaw3d/Dialog.h:     section "Present But 
Cannot Be Compiled"
   configure: WARNING: X11/Xaw3d/Dialog.h: proceeding with the 
preprocessor's result
   configure: WARNING: X11/Xaw3d/Dialog.h: in the future, the compiler 
will take precedence
   configure: WARNING:     ## --------------------------------- ##
   configure: WARNING:     ## Report this to address@hidden ##
   configure: WARNING:     ## --------------------------------- ##

And the dialogs obviously weren't using the Xaw3d widgets.  Not sure 
what this problem is-- I tried various versions of gcc, that made no 
difference.  I guess the Xaw3d library headers are different between my 
current OS (Ubuntu 9.04 AMD64) and the last time I compiled (Ubuntu 7.10 
AMD64).

On windows, moving to snprintf() broke all the microsoft compilers.

Other than that, it looks like we do need the htmlhelp package installed 
as I got undefined references for mingw, cygwin, and all MS compilers 
for MyHelp and HtmlHelp.  MS 6.x (and probably others) do not have 
DWORD_PTR, so the HtmlHelp() prototype in winboard.c breaks there.
