Thanks! (please add a refernce to the CR #6437624
(http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6437624) in
the bug report).

Another problem:
The ksh93 testsuite has a special test script
(usr/src/lib/libshell/common/tests/sun_solaris_getconf.sh) to make sure
Solaris /usr/bin/getconf and ksh93's "getconf" builtin are compatible,
however currenly the test will fail for "SSIZE_MAX" because there is a
difference in the returned values.
Can I get an "exception" from you (I guess you have the authority for
this since you're Sun's standards guru... :-) ) to modify
"sun_solaris_getconf.sh" and filter the SSIZE_MAX test for now, please
(otherwise "sun_solaris_getconf.sh" fails and blows-up the whole test
run... ;-( ) ?

Bye,
Roland
