	* eval.c (r_interpret): In cases Op_var_assign and Op_field_assign,
	include Op_K_getline_redir in the test for skipping the routine.

2011-07-26         John Haque      <j.eh@mchsi.com>

	Fix handling of assign routines for 'getline var'.
	Rework the previous fix for (g)sub.

	* awk.h: New define assign_ctxt for use in Op_var_assign
	and Op_field_assign opcodes. Remove define AFTER_ASSIGN.
	* awkgram.y (snode, mk_getline): Initialize assign_ctxt.
	* builtin.c (do_sub): Adjust to take only the first two
	arguments.
	* eval.c (r_interpret): In cases Op_var_assign and Op_field_assign,
	skip the routine as appropriate. Adjust case Op_sub_builtin.
	* main.c (get_spec_varname): New function.
	* debug.c (print_instruction): Use the new function to get
	special variable name.

	* main.c (varinit): Mark FPAT as NON_STANDARD. Thanks to
	Wolfgang Seeberg <wolfgang.seeberg@yahoo.com> for the report.
	* Makefile.am (EXTRA_DIST): Add po/README, per advice from
	Bruno Haible.
	* dfa.c: Sync with GNU grep.
	* xalloc.h (xzalloc): New function, from GNU grep, for dfa.c.
	* README: Note that bug list is really a real mailing list.

2011-07-16         Arnold D. Robbins     <arnold@skeeve.com>

	* Makefile.am (AUTOMAKE_OPTIONS): Removed.
	* configure.ac (AM_INIT_AUTOMAKE): Removed dist-bzip2 option, on
	advice from Karl Berry.

2011-07-15         John Haque      <j.eh@mchsi.com>

	* awk.h (Op_sub_builtin): New opcode.
	(GSUB, GENSUB, AFTER_ASSIGN, LITERAL): New flags for 
	Op_sub_builtin.
	* awkgram.y (struct tokentab): Change opcode to	Op_sub_builtin
	for sub, gsub and gensub.
	(snode): Update processing of sub, gsub and gensub.
	* builtin.c (do_sub, do_gsub, do_gensub): Nuke.
	(sub_common): Renamed to do_sub. Relocate gensub argument
	handling code from do_gensub to here; Simplify the code a
	little bit. 
	* eval.c (r_interpret): Handle Op_sub_builtin. Avoid field
	re-splitting or $0 rebuilding if (g)sub target string is
	a field and no substitutions were done.
	* pprint (profile.c): Add case for the new opcode.
	* print_instruction (debug.c): Ditto.

2011-07-15         Arnold D. Robbins     <arnold@skeeve.com>

	* awk.h: Typo fix: "loner" --> longer. Thanks to Nelson Beebe.
	* builtin.c (efwrite): Fix flushing test back to what it was 
	in 3.1.8. Thanks to Strefil <strefil@yandex.ru> for the problem
	report.
