Re: RFR: 8155772: gtk3_interface.c compilation error on Ubuntu 12.10

[Kevin Rushforth]

I am not a "R" reviewer for AWT, but using NULL as if it were an int is 
incorrect, so this fix looks good to me.

On my system in this file it appears NULL is "#define (void*)0 which 
causes the error

"error: initialization makes integer from pointer without a cast 
[-Werror]"

Webrev to fix in-line below.
