Log Message:
Add some fixes from GIT and bump revision.  Tested with
xorg-server-1.4.0.90 + Mesa-7.0.2 by me.  Mesa's coming, I promise. ;)
While here, PKG_SKIP_REASON -> PKG_FAIL_REASON, add various preprocessor
definitions to XCOMPMGR_DEFS for the user to play with (sane defaults
have been tested).

Changes include:

    Constified some variables.

    Include getopt.h for getopt(). (in pkgsrc, this uses USE_FEATURES)

    Fixed a bunch of warnings.

    Bug #9762: Fix opacity changes on unmapped windows.
