Hi
Below are the compile time __STRICT_ANSI__ defines for various standards
supported by g++
FrancisANDRE@idefix /usr/include
$ gcc -xc++ -std=c++0x -dM -E - /dev/null | grep ANSI
#define __STRICT_ANSI__ 1
FrancisANDRE@idefix /usr/include
$ gcc -xc++ -std=c++11 -dM -E - /dev/null | grep ANSI

Right now, it is guarded by:

Which means non-strict mode and C99 mode, snprintf was not part of
C++03. I guess (__cplusplus = 201103L) needs to be added to

That's what lead me to use gnu++0x instead.
For -rdynamic, apparently it would work for some simple c++ program,
just not those with new c++11 features. It would be nice to fix it.
Cheers.

Hi,
I'm trying to compile a program under cygwin with latest gcc 4.8.2,
the program compiles fine, but link failed. I'm suspecting this has
something todo with libstdc++ but I couldn't find any document on how
to check libstdc++ version (cygwin setup claim it is version 4.8.2
already).
Your help

I've tried on both 32bit and 64bit clean cygwin install, the result is
same. Something is wrong with cygwin's gcc.
my configure script by default uses g++ --std=c++11, this still have
problem of no snprintf , after I replace all snprintf() with
sprintf() , I've met the same linkage problem
(forgot to say)
this program compile and links fine on g++ 4.6 ,4.7, 4.8 on ubuntu
,centos, freebsd etc without modification.
Cheers.
