conflict with glib 2.21 in GSocket

Attaching the patch (found on Gentoo's BTS) because Trac is currently down.

Patch already applied in wxwidgets2.8 2.8.10.1-0ubuntu1.

From the changelog:

  * Add debian/patches/svn61009_fix_ftbfs.dpatch patch taken from upstream
     SVN rev 61009, fix FTBFS caused by new versions of glib.

But why does building audacity 1.3.9-1 or 1.3.9-2 fail then? You can grab the packages from Debian and try to build them on karmic. You will get this error (in jaunty it builds without problems):

Benjamin,

workaround for you (no real fix though!):
* sudo vi /usr/include/glib-2.0/gio/giotypes.h
* find and comment out line 120 (which reads typedef struct _GSocket GSocket;) by prepending //
* build audacity (works fine for me...)
* edit giotypes.h again and uncomment line 120 (important ;-))

best regards,
Torben

Thank for your idea. Instead of hacking wxgtk, we have patched audacity (version 1.3.9-3). The patch was accepted from upstream, too.
