[PATCH] Cygwin/X: Add configure option for WindowsWM

[Yaakov (Cygwin/X)]

From: Yaakov Selkowitz <yselkowitz at users.sourceforge.net>

WindowsWM support is still experimental, and uses the Rootless extension
which currently breaks the simultaneous build of the other DDXs (see
commit b3415187e92960cbff784108b5a3a8d130dc34c5).  So we disable it by
default for now; once the latter issue is fixed we can make this 'auto'.
