ksh bug fix update

Updated ksh packages that address various bugs are now available.

KSH-93 is the most recent version of the KornShell by David Korn of AT&T
Bell Laboratories. KornShell is a shell programming language, which is
upward compatible with "sh" (the Bourne Shell).

This update addresses the following bugs:

* the built-in mkdir command did not respect the default ACL when creating
directories.

* a memory leak could occur when command output was redirected to a file.

* an incorrect result was returned from a spawned process if the process
was stopped and started by signals.

* a script containing 'set -m' could spin in a stopped state.

* the shell could crash with a segmentation fault when processing a switch
statement.

Users of ksh should upgrade to these updated packages, which resolve these
issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
