  First of all, is there documentation on the debugger?   I used the 
Sally one and I think its great, however, I am not familiar with the
command line options that can be used with it.

  Another Q is when you specify -O4 what exactly does this do?  I 
know that it is Optimization level 4, but the docs don't describe O's that
high.  Is it about the same as O2? 

  When you declare an Array say:

int silly[256];

and then you call:     silly[32] = 5;
Does this sub in the address of silly+32*4  as a number when the program
is started, or does it have to do the addition on the fly?
