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 !
