From fc4aaba8a3b8fe7815e103cc20f2a36d5de7e8ab Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 24 Jan 2021 14:20:33 -0800 Subject: [PATCH] Remove use of include_next from c++ headers Using include_next bypasses the default header search path and lets files later in the include path take priority over earlier files. This makes replacing libc impossible as the default libc headers will occur after the libstdc++ headers, and so be picked up in place of headers inserted at the begining of the search path or appended to the end of the search path. Using include_next is a hack to work-around broken combinations of libraries, and is not necessary in a well constructed toolchain.
