--- Comment #28 from Rene Koecher <rene.koec...@wincor-nixdorf.com> --- (In reply to Giuseppe Ottaviano from comment #26) Giuseppe, is there an easy way you could provide me with your changes to alloc_traits.h? I'd really like to give it a shot against our codebase and see if there's any speedup. I tried to follow along by taking the alloc_traits.h from 225242 adding the suggested diff to compensate for the missing bits in type_traits. While this results in a working drop-in replacement I can not detect any noticable changes in compile time.
