gawk --profile eats parentheses

[Hermann Peifer]

$  gawk --profile '$1=="A" && ( $2=="B" || $3=="C" )'

This results into:

$ cat awkprof.out
       # gawk profile, created Tue Aug 11 16:43:59 2009

       # Rule(s)

       $1 == "A" && $2 == "B" || $3 == "C"     {
               print $0
       }

In awkprof.out, the parentheses are lost which changes the logic of the 
condition.

(I am using gawk 3.1.6).
