Thanks Patrick. I have done this too. However, it was my impression that
the libspeex_armce.lib was cross-compiled in GCC. Building in VS2005
doesn't allow you to take advantage of the ARM assembly optimizations,
since the Microsoft compiler doesn't know how to do that (try defining
ARM5E_ASM or ARM4_ASM and you will see what I mean). At least back in
the 1.1.16 days this seemed to make a big difference for me: the time
taken during a decent sized encode() call was much greater with a
hand-built FIXED_POINT build than it was with libspeex_armce.lib, but
perhaps I was doing something else wrong. I haven't had a chance to see
if that's still the case with 1.2beta1.
