OOP: prophecy nagging flint?

WoW! You guys are posting like mad, I just can't keep up! 

On rereading, I see Dumbledore states that Voldemort's information 
about the prophecy was incomplete. He only heard the first 
part, "...the part fortelling the birth of a boy in July to parents 
who had thrice defied Voldemort. Consequently, he could not warn his 
master that to attack you would be to risk transferring power to you -
again marking you as equal." -Dumbledore, U.S. pg 843

The problem with that statement is that the first part of the 
prophecy (if we are to beleive DD's memory to be intact) does not 
contain the word "boy" or any gender specific word: 

"THE ONE WITH THE POWER TO VANQUISH THE DARK LORD APPROACHES...BORN 
TO THOSE WHO HAVE THRICE DEFIED HIM, BORN AS THE SEVENTH MONTH 
DIES..."

The gender doesn't come into play at all until:

"AND THE DARK LORD WILL MARK *HIM* AS HIS EQUAL, BUT *HE* WILL HAVE 
POWER THE DARK LORD KNOWS NOT"

So how does Voldie know it is a *him* at all if he doesn't know the 
part about marking him as an equal? Maybe there were no girls born at 
the end of July or at least not to those who defied him three times 
(does narrow it down a bit I'm sure). But it annoys me that DD says 
boy and not *the one*. 

Also, assuming Voldie didn't know he was suppose to choose and mark 
his opponent, so to speak, I'm surprised to see no evidence that he 
didn't actively pursue both boys. Instead, it appears he concentrated 
all his efforts on one boy, Harry. Again DD's choice of words is 
intriguing. He says Voldemort chose Harry to be the greatest threat, 
that Voldie "...saw himself in you before he had even seen you."  

Don't know if it's really big deal, but its just been nagging a tad 
at me since I finished reading.

Cheers!
