so what happened so compiler doesn't complains about the initializer before 'CS_Knife_s'

and where does coffset are






GaryJJ (9)
when I compile at cfree it doesn't matter with or without offsets it is always the same

so why does the compiler output from http://codepad.org and cfree output are different
