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

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.

(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.

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 aga
Yes, the sha1 matches.
