Ok this is a quick how to off the top of my head.
Structs.h
Ad something like this 
#define CON_STAT_CNFRM	      (Number)
underneath this somewhere
#define CON_NAME_CNFRM         3
now either find the code where it originally sets up a new charactesr 
stats.  ( I believe handler.c, may be interpreter.c but I don't think so.)
put a while loop into the interpreter.c in the log in for new characters 
that looks something like this
display stats
while (VARIABLE != 'y') || (VARIABLE != 'Y') {
reroll stats
display stats
}
continue with creating character.
That will do it.  I know I didn't give you exact code, but you should be 
able to fill the rest in yourself.
