Hi, i'm trying to build ardour 2.7 on slackware 12.1, haven't had
problems prior to 2.6, but the last few releases fail to compile with
this error:

gcc version is 4.2.3. Any suggestions for a workaround appreciated.
Thanks,

> 
> FEATURES
> 
>     Overall dramatic improvements in OS X GUI performance	
>     New action to rotate editor/mixer window stacking
>     New action to cycle through mouse modes
>     Plugin windows can now have keyboard focus locked to them
>     Add missing extensions to exported files based on selected file type
>     Loop/Range ruler now visible by default
>     Default crossfade is now -3dB cut
>     Crossfade presets changed to include -6dB cut and two S-curves
>          (icons sadly not changed yet)
>     New support for Wiimote control (experimental, disabled by
>           default, and not possible on OS X)
>     Selected tracks are always visible when scrolling through with
>          select-next-track or select-previous-track
>     Skip non-active and hidden tracks with select-previous-track and
>               select-next-track
>     Several new tooltips all over the place and better tooltip colors
>     On OS X, Button2 can be emulated with Ctrl-Option-Button1
>     Busses are never auto-connected to physical inputs
>     Unmodified clicking in canvas rulers now sets playhead position,
>         similar to existing behaviour in the "real" rulers. Use Ctrl-
>         (Linux) or Command (OS X)-click/drag for new markers/ranges.
>     Crossfade-editor specific keybindings: space => play xfade,
>              left-arrow => play fade out, 
>              ctrl-left-arrow => dry fade out,
>              right-arrow => play fade in, 
>              ctrl-right-arrow => dry fade in
>     Drag-n-Drop from OS X Finder now more reliable but no longer
>         supports MP3 or AAC (will be reverted in the future)
>     Start position and Sync position clocks added popup region editor   
>     Better stay-on-top behaviour for certain windows
>     LV2 port notification fix for GUI updating
>     New German translation
>     New post-export nag screen
>     Per-track OSC control of solo/mute/rec-enable and gain
>  
> FIXES
> 
>     Removed suggestion that users can save while disconnected from JACK
>     Corrected reversed handling of "show-editor-mixer" state on startup
>     Fixed crasher caused by changing gain with transport stopped &
>        panner bypassed
>     Correct reverse logic for making h/w monitoring available given
>        h/w capabilities 
>     Fix confusing relabelling of plugin bypass button
>     Prevent double registration of ALSA sequencer ports
>     Correctly initialize JACK timeout parameter when starting JACK
>     Ignore triple-clicks on mute/solo/rec-enable button
>     Momentary solo/mute now works
>     Fix serious error when calculating interpolated Curve values
>        (will cause tiny, almost certainly undetectable changes in
>         automation and fade curves, but may also remove clicks)
>     Fix quoting in TOC files
>     wrap PBD::Thread... signals in a mutex to avoid crashing during
>         startup as multiple threads "emit" the signal
>     Make comboboxes a little bigger on X11
>     B|B|T clocks measuring duration now use zero-based values
>     New regions created by AudioFilters (Reverse/TimeFX/Transpose)
>           inherit all relevant settings of their ancestor
>     Fix for incorrect reading of fade out curve under a few
>           circumstances
>     Catch exceptions while loading AudioUnits
>     Correct some glitches with playhead motion when looping/reversing
>     Fix failure when opening a session by double-clicking the session
>           file icon (OS X)
>     Fix loss of "current dialog" tracking when exiting a dialog via a
>         button (could cause crash on next Ctrl-w)
>     Detect no-installed-JACK on OS X to avoid silent crashes for 
>        new users
>     
> DEVELOPMENT
> 
>    GTK/OSX patch now in SVN
>    Check build host for broken mutex-based glib atomic ops
>    Two versions of clearlooks now in SVN - older, for X11 (crisp!),
>        and newer for OS X (faster!)
> 
> CONTRIBUTORS
