-ansi flag support for g++

I have been compiling a cpp program using following command:
g++ -c -ansi a.cpp with g++ version 4.1.2. I want to know the significance of the -ansi flag and which other higher g++ version supports this flag by default

'supports by default' means that you do not have to specify "-ansi" ?

All versions that I know of require -ansi to be specified. Some other options may imply -ansi

-Wall -pendantic checks everything and is a good idea.
