Hi,
on debugging a crash in ksh93u+ 2012-08-01 and above I've detected
an side effect which cause trouble due not initialized variables
in libast/misc/optget.c. This is fixed in the patch found in the
attachment. Beside this it clearifies the meaning of the variable
n as otherwise the gcc will always trow out a lot of warnings.
