In almost all situations but those when you are creating a final
binary.  The linke can take *significantly* longer if you specify -O1.
On the other hand, compiling without -O might even make the
compilation process slower due to the amount of code generated.  Since
gcc does not perform dead code analysis wiht -O I at least almost
always at least use -O.
