Hello,

I'm cross compiling an asio http server example from x86 linux to mipsel
linux using boost-1.37.0 and gcc 4.1.2.
I've compiled libraries successfully using bjam but the http server code
produces the following errors:

# export ARCH=mipsel
# export CC=mipsel-ssd-linux-gnu-gcc
# export CXX=mipsel-ssd-linux-gnu-g++

... snip ...

I've seen "Disable sync use for arm and hppa" at
https://svn.boost.org/trac/boost/changeset/44440

I've also glanced at detail/sp_counted_base.hpp and
detail/atomic_count_sync.hpp.

Is this a simple matter of avoiding this code as in the changeset, or should
it be written? I don't know much about the MIPS architecture.

Thank you,
Gordon
