* include/c_std/std_cmath.h: To prevent problems overloading g++ builtins, use the double variants from the global namespace before defining float and long double variants in std::. PR c++/5998: * decl.c (cxx_init_decl_processing): Re-enable built-in functions in the g++ front-end. (duplicate_decl): Allow redefinition of anticipated built-ins. Fix inlining problem by over-writing the old DECL_RTL. (lookup_namespace_name): Fail to find an identifier in the specified namespace if its still anticipated. (builtin_function_1): New function split out from builtin_function to create a builtin in the current namespace with given context. (builtin_function): Call builtin_function_1 to define the appropriate builtins in both the std and global namespaces. (select_decl): Don't test for anticipated decls here. (unqualified_namespace_lookup): Instead ignore them whilst searching through scopes and namespaces. * decl2.c (do_nonmember_using_decl): If a using declaration specifies an anticipated built-in function, mark it as no longer anticipated in that scope. (ambiguous_decl): Avoid resolving to an anticipated decl. * lex.c (do_scoped_id): Fail to find an identifier in the global namespace if its still anticipated. * g++.old-deja/g++.other/builtins5.C: New test. * g++.old-deja/g++.other/builtins6.C: New test. * g++.old-deja/g++.other/builtins7.C: New test. * g++.old-deja/g++.other/builtins8.C: New test. * g++.old-deja/g++.other/builtins9.C: New test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
