With "normal" Unix C compilers, -g implies no optimisation. This of
course will make your code run slower (usuallly!) than optimised code.
It's quite difficult to debug code that has been optimised a lot,
although often enough information can be obtained. GNU gcc allows
-O and -g to be combined, and thus (except for disk space) there's
never any reason to not use -g.
