b526ee6116 * src/output.c (output_skeleton): Don't disable M4sugar comments 
too soon: it results in comments being expanded.
* data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
first output.

f6d0c2394c (main): With --trace=time, report times even if a non-fatal error 
occurs.  Formerly, the times were reported in some such cases but not
in others.

Paul Eggert
f956c304c5 (reader): Just return if a complaint has been issued, 
instead of exiting, so that 'main' can report times.

Paul Eggert
e95aed631d (main): Use return to exit, undoing yesterday's change. 
The last OS that we could find where this wouldn't work is
SunOS 3.5, and that's too old to worry about now.

accordingly.
Report the traditional `Try ... --help' message when status != 0.

ea99527d23 Let nondeterministic skeletons be usable with deterministic 
tables.
With the patch, GAWK compiled by GCC without -O2 passes its test
suite using a GLR parser driven by LALR tables.  It fails with -O2
because `struct stat' gives two different answers on my machine:
88 (definition of an auto var) and later 96 (memset on this var).
Hence the stack is badly corrumpted.  The headers inclusion is to
blame: if I move the awk.h inclusion before GLR's system header
inclusion, the two struct stat have the same size.
* src/tables.c (pack_table): Always create conflict_table.
(token_actions): Always create conflict_list.
* data/glr.c (YYFLAG): Remove, unused.

efcb44dd47 (rule_length): New static var. 
Use it to keep track of the rule length in the scanner, since
we can't expect the parser to be in lock-step sync with the scanner.
(handle_action_dollar, handle_action_at): Use this var.
