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
#define __STRICT_ANSI__ 1

FrancisANDRE@idefix /usr/include
$ gcc -xc++ -std=gnu++11 -dM -E - < /dev/null | grep ANSI

FrancisANDRE@idefix /usr/include
$ gcc -xc++ -std=c++98 -dM -E - < /dev/null | grep ANSI
#define __STRICT_ANSI__ 1

All but c++11 define __STRICT_ANSI__. That's why your sample does not
compile. This a issue with the cygwin includes that should provide snprintf
for c++11 also not only for other standards.
