re PR c++/23333 (accepts invalid pure specifier)
2005-12-22 Volker Reichelt <reichelt@igpm.rwth-aachen.de>
PR c++/23333
* include/cpplib.h: Add PURE_ZERO to flags for the cpp_token structure.
* c-lex.c (c_lex_with_flags): Add PURE_ZERO to cpp_flags if
number is a single digit '0'.
* parser.c (cp_parser_pure_specifier): Check for PURE_ZERO to
identify a single '0'.
* g++.dg/parse/error25.C: Add more tests.
