Take them out, and precede this code with:

One correct answer to the question is ANSI C. In ANSI C++ and Java at 
least, as was probably the rationale for ANSI C, the idea is to not pay 
for a variable you never use if a particular run of the program does not 
reach that loop.

Incidentally, at least in C89 would Mike's example not run the risk of x 
and inty having different datatypes?
unsigned int x;
unsigned inty;
would be safer.
