Hi,
I thought I'd already fixed this a year or so ago. Looking at my system, I see
this in cdefs.h:
/* C++11 exposes a load of C99 stuff */
#if defined(__cplusplus) __cplusplus = 201103L
#define __LONG_LONG_SUPPORTED
#ifndef __STDC_LIMIT_MACROS
#define __STDC_LIMIT_MACROS
#endif
#ifndef __STDC_CONSTANT_MACROS
#define __STDC_CONSTANT_MACROS
#endif
#endif
So, if you're compiling C++ and the C++ standard is C++11 or later, we define
the __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS macros. If it's C++98, you
can define them yourself.
Do you have a test case where this doesn't work?

When including stdint.h in c++ we can #define __STDC_LIMIT_MACROS so
that we get macros like INT32_MAX defined.
Also related is __STDC_CONSTANT_MACROS
I have recently found that the need for these has been removed within
the c++11 standard.
This year old bug report was to update glibc to this end -
https://sourceware.org/bugzilla/show_bug.cgi?id=15366
Also of note is that Apple removed the use of this macro from OSX with
the release of 10.9 over a year ago
http://www.opensource.apple.com/source/xnu/xnu-2422.1.72/EXTERNAL_HEADERS/stdint.h
I believe as we push to use llvm's libc++ and support for c++11 we
should also make sure the rest of our sources are kept up to date as
well.
Are there any other changes within c++11 or c++14 that we should be
looking to update?
