 Surprising Interpretations of Code
 ----------------------------------
 
    The `-Wsurprising' option can help find bugs involving expression
 evaluation or in the way `DO' loops with non-integral iteration
 variables are handled.  Cases found by this option might indicate a
 difference of interpretation between the author of the code involved,
 and a standard-conforming compiler such as `g77'.  Such a difference
 might produce actual bugs.
 
    In any case, changing the code to explicitly do what the programmer
 might have expected it to do, so `g77' and other compilers are more
 likely to follow the programmer's expectations, might be worthwhile,
 especially if such changes make the program work better.
