N3472 binary constants
N3472 binary constants
* include/cpplib.h (struct cpp_options): Fix a typo in user_literals
field comment. Add binary_constants field.
* init.c (struct lang_flags): Add binary_constants field.
(lang_defaults): Add bin_cst column to the table.
(cpp_set_lang): Initialize CPP_OPTION (pfile, binary_constants).
* expr.c (cpp_classify_number): Talk about C++11 instead of C++0x
in diagnostics. Accept binary constants if
CPP_OPTION (pfile, binary_constants) even when pedantic. Adjust
pedwarn message.
* g++.dg/cpp/limits.C: Adjust warning wording.
* g++.dg/system-binary-constants-1.C: Likewise.
* g++.dg/cpp1y/system-binary-constants-1.C: New test.
