How to know default flags used in specific gcc version ? I am looking
for difference between 3.4.3 and 4.1.1 These two have some difference
regarding -nosse option but how can I find this ?

try something like:
echo "" | gcc -E -v - 2>&1 | grep -i cc

and find the line like below:

/usr/lib/gcc/i686-linux-gnu/4.6/cc1 -E -quiet -v -imultilib .
-imultiarch i386-linux-gnu - -mtune=generic -march=i686
-fstack-protector

(that's mine on Core Duo, Linux Mint 13 32 bit)
