 So I performed two tests:
 
 - with the libexpat libraries copied from my old X11R7:
        Unfortunately no change
 
 - ssh in the box after startx:
 
 Interestingly here I noticed that X was simply not running.  Obviously,
 trying to get an X client to connect to DISPLAY :0.0 also then failed.
 This unfortunately suggests that the video mode is changed, that X11
 crashes or quits, and the video state is then left stale in graphics
 mode with a blank screen.  I could also switch to the VT and type
 commands which succeeded, but I couldn't see any output, of course,
 another indication that X is simply no longer running at that point.
 
 A next test will be piping the output of startx to a file.  I guess
 that I could also over ssh try to start it under gdb, but I'd have to
 rebuild it with symbols.  I'm not sure if I'll have the necessary time
 today to do that, but I'll report with more info when I do.
 
 To build a system with debug symbols, is it sufficient to add "-O0 -g"
 to CFLAGS and "-g" to LDFLAGS?  Or is there another recommended
 approach?
 
 Thanks,
