From c60e94a70efc44dd419ec5119dad3aa7813949d3 Mon Sep 17 00:00:00 2001 From: Neil Booth Date: Thu, 19 Jul 2001 06:12:50 +0000 Subject: [PATCH] c-lex.c (c_lex): Remove CPP_INT, CPP_FLOAT cases. * c-lex.c (c_lex): Remove CPP_INT, CPP_FLOAT cases. * c-parse.in (yyerror, _yylex): Similarly. * cppexp.c (parse_number, parse_defined, lex, _cpp_parse_expr): Don't use CPP_INT, CPP_FLOAT; CPP_NUMBER is enough. Update comments. * cpplib.h (CPP_INT, CPP_FLOAT): Remove. * cp/spew.c (read_token, yyerror): Remove CPP_INT, CPP_FLOAT cases.
