* iomanip.h: Use __extension__ for `extern' explicit template instantiations. * sinst.cc: Don't explicitly instantiation string_char_traits<char>. * cinst.cc: Likewiwse, for complex<float>, complex<double>, complex<long double>. * extend.texi: Remove description of extension to explicit instantiation that is now endorsed by standard C++. * decl2.c (grok_array_decl): Add comment. (mark_used): Don't instantiate an explicit instantiation. * friend.c (make_friend_class): Remove bogus comment. Fix check for partial specializations. * pt.c (check_explicit_specialization): Don't SET_DECL_EXPLICIT_INSTANTIATION here. (mark_decl_instantiated): Or here. (do_decl_instantiation): Do it here, instead. Add checks for duplicate explicit instantiations, etc. Tidy. (do_type_instantiation): Likewise. (instantiate_decl): Improve comments. Complain about explicit instantiations where no definition is available. * cp-tree.h (ansi_null_node): Remove. * call.c (build_over_call): Warn about converting NULL to an arithmetic type. * cvt.c (build_expr_type_conversion): Likewise. Use null_ptr_cst_p instead of expanding it inline. * decl.c (ansi_null_node): Remove. (init_decl_processing): Make null_node always have integral type. * except.c (build_throw): Warn about converting NULL to an arithmetic type. * lex.c (init_parse): Remove handling of ansi_null_node. * pt.c (type_unification_real): Don't convert NULL to void* type. * typeck.c (build_binary_op_nodefault): Fix NULL warnings. (convert_for_assignment): Warn about converting NULL to an arithmetic type. (convert_for_initialization): Likewise. From-SVN: r21915
