	* codegen.c (output_call): for static calls only generate parameters
	  up to the maximum number of the call, otherwise the static calls
	  cannot be resolved at compile time.
	  Note: currently only done for system library calls, we'd need an
	  external repository for doing this with other calls, too.
	* typeck.c (cb_emit_call): warn if more than the max parameters is
	  used for system library calls

	  for early/late aborting depending on number of errors, defaulting
	  to the old value: 100
	* cobc.c: added -W[no-]fatal-errors for aborting on first error
	  note: this option takes precedence over -fmax-errors

2017-04-27  Sergey Kashyrin <ska@kiska.net>

	* parser.y: Fix for CALL-CONVENTION (was broken)

	  snprintf returns -1 in MSC and on HPUX if max is reached

2017-04-13  Simon Sobisch <simonsobisch@gnu.org>

	* cobc.c (print_fields, print_88_values): removed indent parameter as
	  we no longer indent by level number

	  prototype.

2017-04-17  Edward Hart <edward.dan.hart@gmail.com>

	* cobc.c (process_translate): reverse program list in place so that
	  current_program doesn't point to last program in file (see bug #265).
	* codegen.c: reinstated local variable current_prog removed in
	  r1309. (codegen) would leave current_program pointing to the last
	  program in a file, from which you cannot get the first program. This
	  caused the listing code to break (bug #265) because it assumed
	  current_program would point to the first program in the file.

2017-03-19  Simon Sobisch <simonsobisch@gnu.org>

	* codegen.c: bug #364 moved (output_initialize_chaining) out of
	  (output_initialize_one), special handling for chaining only during
	  program initialization
	* codegen.c (output_internal_function): [bugs:#354] generate code for
	  raising COB_FERROR_CHAINING when CHAINING program is not the
	  main program instead of when it is called the second time

2017-03-19  Dave Pitts <dpitts@cozx.com>

	* cobc.h, pplex.l: Restored copy_tail functionality. The copy books were

	* field.c, tree.h (cb_validate_renames_item): strengthened 66-level
	  syntax checks.

2016-07-18  Edward Hart <edward.dan.hart@gmail.com>

	* parser.y (screen_or_device_display): changed permitted DISPLAY
	  combinations (to follow Micro Focus). Now screens must have their own,
	  individual displays and cannot be mixed with the display of

	* parser.y, typeck.c: added support for LINE/COLUMN/AT 0 and removed
	  requirement of LINE/COLUMN clause on CRT displays.
	* config.def: added accept-display-extensions to enable/disable
	  the above and any other non-standard extensions.

	  were not detected.

2016-07-17  Brian Tiffin <btiffin@gnu.org>

	* codegen.c: when emitting source for a function entry, if cob_call_params
	  is zero, and cob_module is not set, set cob_call_params to the number of
	  arguments in GnuCOBOL using_list. Need to document that C can't call a
	  GnuCOBOL function with zero arguments if GnuCOBOL expects at least one,
	  even if all are optional from the GnuCOBOL perspective.  Except for that
	  edge case, this fixes bug #208 (and possibly others).
	* codegen.c: allow for ENTRY lookup inside main module.

2016-07-15  Edward Hart <edward.dan.hart@gmail.com>

	* scanner.l, pplex.l: fixed bug #269. GnuCOBOL now gobbles redundant

	  PROGRAM_NAME's from scanner inside the identification division.

2016-07-06  Edward Hart <edward.dan.hart@gmail.com>

	* typeck.c: fixed bug #264, where fields of category CB_CATEGORY_UNKNOWN
	  were rejected in the AT clause despite being numeric (or having only
	  numeric children).
	* typeck.c (valid_screen_pos): removed extension to AT clause where less
	  than 4 digits was permitted (I'd added this because I thought leading
	  zeroes were truncated from literals).

2016-06-30  Edward Hart <edward.dan.hart@gmail.com>

	* pplex.l (is_condition_directive_clause): fixed bug #263 where >>IF's
	  where not detected inside false >>IF's.

	  copy_list_replace.

2016-06-28  Dave Pitts <dpitts@cozx.com>

	* cobc.c: Fixed mystery edits that broke FILE and FILLER listing.

2016-06-27  Edward Hart <edward.dan.hart@gmail.com>

	  replacing while loops with for where appropriate) and simplified and
	  modularised code.

2016-06-25  Edward Hart <edward.dan.hart@gmail.com>

	* pplex.l: fixed bug #248, where any directive was evaluated inside the
	  false part of a conditional directive. Restricted this to ELSE,
	  END(-IF), WHEN, etc.
	* cobc.c, error.c: fixed style issues: non_snake_case variable names,
	  non-K&R or missing braces, no space before parentheses or around + or
	  -, spaces instead of tabs, variable declarations without names
	  indented and more than one declaration per line.
	* cobc.c (print_program_code): fixed corrupt doubled-linked list error
	  caused when cb_listing_files and cb_current_file pointed to the same
	  struct and cb_current_file was freed.
	* pplex.l: moved COPY-specific code to get_new_listing_file and added
	  call to it from INCLUDE.
	* cobc.h, parser.y, pplex.l, ppparse.y: moved PENDING macro to cobc.h as
	  CB_PENDING.

2016-06-22  Edward Hart <edward.dan.hart@gmail.com>

	  is used which is reserved in another dialect (see Wish List #107).
	* parser.y (_identification_header): reinstate ID DIVISION option.
	* parser.y (setup_program): fixed bug #255, where function could be
	  defined within a program.

2016-06-21  Ron Norman <rjn@inglenet.com>

	* error.c (print_error): fixed to verify 'file' is NOT NULL before using it
	* cobc.c: FR #138 added checks for some env vars which are not allowed to
	  have PATHSEP_CHAR in them

2016-06-20  Dave Pitts <dpitts@cozx.com>

	* cobc.c, cobc.h, error.c, pplex.l, ppparse.y: Added support for compiler
	  listings.

2016-06-20  Simon Sobisch <simonsobisch@gnu.org>

	* codegen.c (output_internal_function): fixing bug #234 segfault by
	  generating code for setting not passed parameter pointers to NULL as if

	* ppparse.def: Added compiler constants GNUCOBOL (alias for OPENCOBOL)
	  and GCCOMP (alias for OCCOMP)

	* typeck.c (cb_validate_program_environment): FR #67 output duplicate values
	  in errornous alphabet-names at correct error position

	  begin_implicit_statement causing exceptions to be set to off before
	  checking which exception handler to go to.
	* codegen.c: fixed another cause of bug #243, where only EC-IMP-DISPLAY
	  (and not EC-SCREEN) triggered the ON EXCEPTION phrase. As part of
