Default flags with -O2

[Anticipating a Reply]

Hello ,

 Thanks .

 I was referring the gcc 3.2.3 Manual .
It does not elaborate on the flags as 
given in the 3.3 Manual does . 

 Hope the information on flags given in 
gcc 3.3 manual holds good also for gcc 3.2.3 .

 Just curious to know if this information 
can be retrieved at runtime during compilation 
time .

Cheers !
