What's weird about that is that in order to do variable declarations 
within the definition of a for loop, I need to pass -std=c99 to GCC.  
However, I don't need to do that in order to simply declare variables 
later in the function.  That would lead me to believe that C99 is not 
required to do so.  Could it possibly be a C89 thing?  How far back is 
considered ANSI C?
