gcc/cp: * decl.c (grokfndecl): If ::main is found not to return int, correct it after issuing a diagnostic. (grokdeclarator): If the incoming type was error_mark_node, do not complain about declaring something with no type. (start_function): Change check for ::main not returning int to an assertion, as grokfndecl now catches this when the user did it. * init.c (perform_member_init, sort_mem_initializers) (emit_mem_initializers): Make most diagnostics be issued on the line of current_function_decl, not whatever the current input line is. * parser.c (cp_lexer_peek_token_emit_debug_info): Surround definition and declaration with #ifdef ENABLE_CHECKING. Avoid unnecessary use of fprintf. (cp_lexer_print_token, cp_lexer_debug_stream): Adjust stub definitions to avoid warnings. (cp_lexer_new_main): Add assertion that first token is not a padding token. (cp_lexer_new_from_token_array): Fold into ... (cp_lexer_new_from_tokens): ... here. Add assertion that first token is not a padding token. (cp_lexer_set_source_position_from_token): Move nearer to callers. Remove unused lexer argument. (cp_lexer_peek_token): Just print debugging report (if enabled) and return lexer->next_token. (cp_lexer_skip_purged_tokens): Delete. (cp_lexer_next_token_is, cp_lexer_next_token_is_not): Make inline, simplify bodies. (cp_lexer_peek_nth_token): Add debugging report a la cp_lexer_peek_token. (cp_lexer_consume_token): Correct commentary. Advance over purged tokens here. Set current source position here, from token to be returned. Avoid unnecessary use of fprintf. (cp_lexer_purge_token): Advance next_token pointer over this and subsequent purged tokens. (cp_parser_error): Adjust source position to that of the peeked token. (cp_parser_push_lexer_for_tokens, cp_parser_pop_lexer): New functions. (cp_parser_string_literal): Remove some excessive cleverness. (cp_parser_enum_specifier): Call start_enum before consuming the opening brace. (cp_parser_member_declaration): Make the "extra semicolon" diagnostic consistently-worded with the other place this is diagnosed. Explicitly set the diagnostic location to the location of the offending semicolon. (cp_parser_enclosed_template_argument_list): Use %</%> quoting in diagnostics. Do not use cp_parser_require. Set location of diagnostics about improper use of '>>' to location of offending token. (cp_parser_late_parsing_for_member): Use cp_parser_push_lexer_for_tokens and cp_parser_pop_lexer. (cp_parser_late_parsing_default_args): Likewise. Manually move some logic outside the loop. gcc/testsuite: * g++.dg/ext/complit1.C * g++.dg/other/error2.C * g++.dg/other/nontype-1.C * g++.dg/parse/crash11.C * g++.dg/parse/crash12.C * g++.dg/parse/error15.C * g++.dg/parse/error4.C * g++.dg/parse/tmpl-outside1.C * g++.dg/parse/too-many-tmpl-args1.C * g++.dg/template/dependent-expr3.C * g++.dg/template/error10.C * g++.dg/template/instantiate1.C * g++.dg/template/vtable2.C * g++.dg/warn/Wshadow-1.C * g++.dg/warn/weak1.C * g++.old-deja/g++.brendan/crash16.C * g++.old-deja/g++.brendan/crash18.C * g++.old-deja/g++.brendan/crash48.C * g++.old-deja/g++.brendan/crash49.C * g++.old-deja/g++.brendan/crash55.C * g++.old-deja/g++.brendan/crash56.C * g++.old-deja/g++.brendan/crash8.C * g++.old-deja/g++.brendan/enum11.C * g++.old-deja/g++.brendan/enum8.C * g++.old-deja/g++.brendan/enum9.C * g++.old-deja/g++.brendan/friend3.C * g++.old-deja/g++.brendan/misc14.C * g++.old-deja/g++.bugs/900402_02.C * g++.old-deja/g++.bugs/900404_03.C * g++.old-deja/g++.bugs/900404_04.C * g++.old-deja/g++.bugs/900428_03.C * g++.old-deja/g++.jason/crash4.C * g++.old-deja/g++.jason/overload21.C * g++.old-deja/g++.jason/redecl1.C * g++.old-deja/g++.jason/report.C * g++.old-deja/g++.jason/rfg10.C * g++.old-deja/g++.jason/template30.C * g++.old-deja/g++.law/arm12.C * g++.old-deja/g++.law/ctors5.C * g++.old-deja/g++.law/cvt20.C * g++.old-deja/g++.law/init10.C * g++.old-deja/g++.law/init8.C * g++.old-deja/g++.law/visibility17.C * g++.old-deja/g++.law/visibility7.C * g++.old-deja/g++.mike/net8.C * g++.old-deja/g++.mike/p646.C * g++.old-deja/g++.mike/p700.C * g++.old-deja/g++.mike/p701.C * g++.old-deja/g++.mike/p811.C * g++.old-deja/g++.ns/template13.C * g++.old-deja/g++.other/array3.C * g++.old-deja/g++.other/crash25.C * g++.old-deja/g++.other/dtor3.C * g++.old-deja/g++.other/dtor4.C * g++.old-deja/g++.other/main1.C * g++.old-deja/g++.other/warn7.C * g++.old-deja/g++.pt/crash11.C * g++.old-deja/g++.pt/crash36.C * g++.old-deja/g++.pt/spec22.C * g++.old-deja/g++.pt/spec9.C * g++.old-deja/g++.pt/ttp52.C * g++.old-deja/g++.robertl/eb103.C * g++.old-deja/g++.robertl/eb121.C * g++.old-deja/g++.robertl/eb22.C * g++.old-deja/g++.robertl/eb8.C: Update locations and/or regexps of dg-error markers.

file: libstdc++-v3/README
New users may wish to point their web browsers to the file
documentation.html in the 'docs/html' subdirectory. It contains brief
building instructions and notes on how to configure the library in
interesting ways.
Instructions for configuring and building appear in
docs/html/install.html.
This directory contains the files needed to create an ISO Standard C++
Library.
It has subdirectories:
docs
Files in HTML and text format that document usage, quirks of the
implementation, and contributor checklists.
include
All header files for the C++ library are within this directory,
modulo specific runtime-related files that are in the libsupc++
directory.
include/std
Files meant to be found by #include <name> directives in
standard-conforming user programs.
include/c
Headers intended to directly include standard C headers.
[NB: this can be enabled via --enable-cheaders=c]
include/c_std
Headers intended to include standard C headers, and put select
names into the std:: namespace.
[NB: this is the default, and is the same as --enable-cheaders=c_std]
include/c_shadow
Headers intended to shadow standard C headers provided by an
underlying OS or C library, and other headers depended on directly
by C++ headers (e.g. unistd.h). These are meant to wrap the names
defined there into the _C_legacy namespace.
[NB: this can be enabled via --enable-cheaders=c_shadow]
include/bits
Files included by standard headers and by other files in
the bits directory.
include/backward
Headers provided for backward compatibility, such as <iostream.h>.
They are not used in this library.
include/ext
Headers that define extensions to the standard library. No
standard header refers to any of them.
scripts
Scripts that are used during the configure, build, make, or test
process.
src
Files that are used in constructing the library, but are not
installed.
testsuites/[backward, demangle, ext, performance, thread, 17_* to 27_*]
Test programs are here, and may be used to begin to exercise the
library. Support for "make check" and "make check-install" is
complete, and runs through all the subdirectories here when this
command is issued from the build directory. Please note that
"make check" requires DejaGNU 1.4 or later to be installed. Please
note that "make check-script" calls the script mkcheck, which
requires bash, and which may need the paths to bash adjusted to
work properly, as /bin/bash is assumed.
Other subdirectories contain variant versions of certain files
that are meant to be copied or linked by the configure script.
Currently these are:
config/abi
config/cpu
config/io
config/locale
config/os
In addition, two subdirectories are convenience libraries:
libmath
Support routines needed for C++ math. Only needed if the
underlying "C" implementation is non-existent, in particular
required or optimal long double, long long, and C99 functionality.
libsupc++
Contains the runtime library for C++, including exception
handling and memory allocation and deallocation, RTTI, terminate
handlers, etc.
Note that glibc also has a bits/ subdirectory. We will either
need to be careful not to collide with names in its bits/
directory; or rename bits to (e.g.) cppbits/.
In files throughout the system, lines marked with an "XXX" indicate
a bug or incompletely-implemented feature. Lines marked "XXX MT"
indicate a place that may require attention for multi-thread safety.
