coredump upon X "Can't open display" error

[mhpower]

I'm using 1.0.0 with Linux 2.0.35, libc 5.4.44, XFree86 3.3.1, XForms
0.88, and libXpm 4.7 -- lyx dumps core if it can't open the X display:

  Program terminated with signal 11, Segmentation fault.
  ...
  #0  0x80568f4 in LyXGUI::LyXGUI (this=0x8292df0, owner=0xbffff824, argc=0xbffff848, 
argv=0xbffff860, GUI=true) at lyx_gui.C:182
  182             fcntl(ConnectionNumber(fl_get_display()), F_SETFD, FD_CLOEXEC);

I think the attached patch will address the issue.
