making the compiler more picky

[ArKHaM]

Hello again list,
     I am running on Mandrake linux box and was wondering if there was a way
to make the compiler more picky.  Want I want is the compiler to check each
_user_made_ variable for initialization before it's assigned or used.
Mainly the argument values in functions.  IE:

void do_foo(CHAR_DATA *foo, char *THISargument)

char arg[MSL];

I want it to check for:

arg[0] = '\0';

the initilization of the arg variable.  Can this be done with Makefile?  Or
do I need root access?
