I do not want to start an optimization discussion thread
here, but I want to tell you my opinion.

My experiance showd me, that in most common usage the use
of the '-O' switch is enough.

That means: If you want to have fast compiling, disable
the '-O' option, and if you want to have a small and fast
executable, enable '-O2'.

All the other optimization options are very special and
only increase the speed or decrease the size for special
programs.

Ans as a summary of the above, I see no neccessary for
adding additional buttons, since you can do it mostly
with the '-O' switch.

Hey, for checking the syntax there is a separate switch
to gcc.

Making a stripped exe is usefull only if you know exactly
what you do. I never strip my exe's except in the following
cases:

1) Writing such simple programs like the "Hello world"
2) Making a distribution.
3) I'm abolutely sure, that my program has no bugs,
   but this will never happen.
