+<h3><a name="redhat">Warning about GTK libraries supplied with RedHat</a></h3>
+
+It seems that some versions of RedHat include a badly patched version of GTK (not wxGTK)
+which causes some trouble with wxWindows' socket code. Common symptoms are that when
+a client tries to establish a connection to an existing server which refuses the request,
+the client will get notified twice, first getting a LOST event and then a CONNECT event.
+This problem can be solved by updating GTK with an official distribution of the library.

+
+"The important thing is the libc version that your app
+is linked against. The most recent version is 2.2.5
+and programs linked against it will not run with version
+2.1.X so that you will fare best if you compile your app
+on a 2.1.X system. It will then run on practically all
+Linux distros (if you link you app statically against
+the image libraries and std C++ lib)."
