[Bug 20070] New: Wine applications can't set an gamma value

http://bugs.winehq.org/show_bug.cgi?id=20070

Summary: Wine applications can't set an gamma value
           Product: Wine
           Version: 1.1.29
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P4
         Component: winex11.drv
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

While testing for regressions in "The Sims 3" I noticed that the screen is
darker than usual. It seems like X_XF86VidModeSetGamma and
X_XF86VidModeSetGammaRamp are not defined anymore. They get defined in
X11/extensions/xf86vmproto.h on my system, including it in
dlls/winex11.drv/xvidmode.c enables "The Sims 3" and other games to set a gamma
value again.
I don't know exactly why it doesn't get defined anymore. Maybe some
restructuring in xf86vidmodeproto? Or maybe a bug in my distribution?

Running an up-to-date Arch Linux x86_64 installation here, latest Wine from
GIT.
