Just to give the OP an idea: xeyes still works, an application that probably *predates* 1992. So does xterm. Probably the *oldest* known X11 application there is. I expect twm is still available, should anyone really want to go there. Yes, the *core* X11 library has been unchanged for a very long time. It is like the wheel -- nobody has really updated the basic shape (round) in *thousands* of years. The OP is more likely to get grumblings from the C compiler, mostly relating to the migration from K&R C to ANSI C and modernizaions of the C library (things should still compile, just all sorts of anoying warnings). The only other issue would be imake (is that still used?) and Motif (but there is OpenMotif). > > -- Robert Heller -- 978-544-6933 / hel...@deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
