Symptoms:
	PHCO_27559:
	( SR:8606268592 CR:JAGae32830 ) Duplicate
	( SR:8606276719 CR:JAGae40794 )
	awk(1) reports incorrect error messages like "awk: xxxxxx
	cannot be used as an array" even if run on scripts that have
	proper array variables defined.

	( SR:8606257112 CR:JAGae21422 )
	In multibyte environment awk(1) recognizes some extra
	characters in conjunction with blank, tab and newline as
	default field separators.

	( SR:8606212881 CR:JAGad82068 )
	awk(1) doesn't recognize numbers with leading blanks in
	relational operations.

Defect Description:
	PHCO_27559:
	( SR:8606268592 CR:JAGae32830 ) Duplicate
	( SR:8606276719 CR:JAGae40794 )
	awk(1) can generate incorrect error messages due to improper
	internal memory management.

	Resolution:
	For proper internal memory management in awk(1), a new
	variable has been introduced to differentiate between active
	and unused (free) memory nodes.

	( SR:8606257112 CR:JAGae21422 )
	awk(1) documentation says that default field separators are
	blank, tab and newline. But for multibyte locale awk(1)
	recognizes other characters too as field separator.
	Steps:
	$ export LANG=ja_JP.SJIS
	$ echo "This i\rs\tawk t\vest" | awk '{printf("%s/%s/%s/
	  %s\n",$1,$2,$3,$4);}'
	This/i/s/awk   <=== This is wrong

	The output should be :
	s/awk/t
	       est

	Resolution:
	For multibyte locale, awk(1) used to treat the <space> set
	as field separator set. Instead of this, changes have been
	made to check <blank> set (containing blank,\t and alternate
	blank characters) and newline character.

	( SR:8606212881 CR:JAGad82068 )
	In case any of the operands in relational operation contain
	leading blanks, awk(1) performs string comparison. This is
	true even if the operand has a numeric value, after ignoring
	the leading and trailing blanks.
	Steps:
	$ export UNIX95=1
	$ awk 'BEGIN {a=" 0.1";if(a>0.01){print "True"}else{print
	  "False"}}'
	False   <=== It should print "True"
	$

	Resolution:
	Changes have been made to perform string comparisons only
	when both the operands are strings else if any of the
	operands is numeric, numeric comparison is carried out. This
	fix is required to conform to UNIX95 standards, hence it is
	available only when the UNIX95 flag is set. If UNIX95 flag
	is unset then awk will retain the earlier behavior.

Enhancement:
	No
