Each of the postinstall scripts are installed as part of a package to perform
some aspect of installation that can not be done statically during the package
build as it may depend on dynamic aspects of each user's installation.
The Cygwin Setup program will normally rename the non-permanent (not starting
[0z][p-t]_...) postinstall scripts with suffix .done after successful execution,
so failure of the postinstall script is the usual reason they are not suffixed,
and that should be captured in /var/log/setup.log and /var/log/setup.log.full at
the end of each Setup run, and may be checked using:

	$ fgrep -B1 'abnormal exit: exit code=' /var/log/setup.log*
