<div>
<pre>stdlib_exception.cpp does:
#define _LIBCPP_BUILDING_LIBRARY
#define _LIBCPP_BUILDING_NEW
#include <new>
#include <exception>
debug.cpp does:
#include "__config"
#include "__debug"
If you don't manually define _LIBCPP_BUILDING_LIBRARY while building debug.cpp
(done in CMakeLists.txt, but we have our own BUILD.gn for libc++), then you get
a bunch of errors. Either way is fine, but shouldn't libc++ and libc++abi be
consistent about if they want this to be defined via a -D switch or if they
define it themselves where needed?</pre>
