Enabling SHM support in default build of XWin.exe

[Harold L Hunt II]

Ralf Habacker sent some patches on 2003/09/05 that I am working on 
getting committed to the XFree86 CVS tree.  Those two patches are here:

http://cygwin.com/ml/cygwin-xfree/2003-09/msg00092.html
http://cygwin.com/ml/cygwin-xfree/2003-09/msg00090.html


I have opened Bug 698 in XFree86's Bugzilla to track the fixing of the 
xf86bigfont extension initialization:

http://bugs.xfree86.org/show_bug.cgi?id=698


After Bug 698 is committed I will be adding a function (from Ralf's 
patches) to XWin.exe to check whether or not the IPC daemon is running, 
then I will be adding a call to that function in the initialization of 
the SHM and xf86bigfont extensions (again, per Ralf's patch).

This should result in a build of XWin.exe that supports SHM when the IPC 
daemon is running, but is not hindered when the IPC daemon is not running.


This will be a nice addition, as it will allow Ralf to stop distributing 
ancient copies of XWin.exe for KDE on Cygwin.  :)


My one question is this: KDE on Cygwin (last I checked) is also 
distributing a handful of X libraries (X11?) that need SHM support as 
well, can SHM be dynamically enabled/disabled for these libraries, or 
are they going to have to be built in two different flavors still?


Regardless of the answer, adding dynamic SHM support to XWin.exe will 
solve the majority of the problems of KDE on Cygwin distributing custom 
files.  XWin.exe gets updated so frequently that it would be an 
unreasonable burden for them to try to keep their copy up to date.
