A couple of xtreme-header-* modules tests began ICEing in C++23 mode ever since r13-2650-g5d84a4418aa962 which introduced into <ranges> a dependently scoped friend declaration: friend /* typename */ _OuterIter::value_type; This happens because the streaming code assumes a TYPE_P friend must be a class type, but here it's a TYPENAME_TYPE, which doesn't have a TEMPLATE_INFO or CLASSTYPE_BEFRIENDING_CLASSES. This patch tries to correct this in a minimal way. gcc/cp/ChangeLog: * module.cc (friend_from_decl_list): Don't consider CLASSTYPE_TEMPLATE_INFO for a TYPENAME_TYPE friend. (trees_in::read_class_def): Don't add to CLASSTYPE_BEFRIENDING_CLASSES for a TYPENAME_TYPE friend. gcc/testsuite/ChangeLog: * g++.dg/modules/typename-friend_a.C: New test. * g++.dg/modules/typename-friend_b.C: New test.

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*.
