Don't do that.  The C language spec is ambiguous as to what happens to 
the variable x when you do write code like
	x = x--;
and the compiler is free to do whatever it darn well pleases.  And 
whatever it does is probably not what you expect it to do.  Write that 
code as either:
	x--;
or
	x = x - 1;
