Yes, they will, given the same patches are used. Note that the script is not 
intelligent enough to detect new patches as the appear, and include a few
patches which were (at the time i published the script) not yet in released,
or are of my own making (and may never be released)

Furthermore the script builds gcc-4.3.3 and not 4.3.2 so this could
make a difference too.
