Description:
When using "Maximize" command of fvwm 2.6.1 or fvwm-devel 2.7.0 will make focused window fill up all screens even if Xinerama enabled both in Xorg and fvwm's config. That means the "Xinerama" command in fvwm 2.6.0 or 2.7.0 from extra repo does not work.
I've checked the PKGBUILD file from abs, and there are no "--disable-xinerama" option. and When I built fvwm from source using abs and installed it, the "Maximize" command works as usual: when maximizing a window, it will fill up the screen which it on.
It seems the packages doesn't link against libXinerama, so what ever the "Xinerama" option's value is, fvwm will take all screens managed by xorg-server as a large logical screen. But when I compile it by myself it will be fixed.

Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:
1. install fvwm from repo
2. edit the ~/.fvwm/config or ~/.fvwm2rc file, add "Xinerama on"
3. edit /etc/X11/xorg.conf, add the following line into "ServerLayout" section:
Option "Xinerama" "on"
4. start fvwm and click the maximize button on any window's title bar.
