Using command line arguments when compiling with gcc in code blocks

So my question is simple.

I want to compile a C project file in the gcc 4.4.8 compiler.

In the cmd window, I can type:

gcc -std=c99 -O2 -DCONTEST -s -static -lm name.c -o name.exe

      

        
        
        
      

    

In Code :: Blocks, how do I change the compiler defaults from the above? I wanted to create a c file and I am getting errors like

error: 'for' loop initial declarations are only allowed in C99 mode|
