Peter,

thanks for the detailed response, works fine now (currently, no need for
multi-threading in my application).

For the next release, I can test the new version with my compiler setup.

Roland,

You have two options:

* If your program doesn't use threads, #define BOOST_DISABLE_THREADS to
disable thread safety;

* Otherwise, modify boost/detail/atomic_count.hpp to not use the
Linux-specific version by changing the line

#elif defined(linux) || defined(__linux) || defined(__linux__)

to

#elif defined(BOOST_USE_ASM_ATOMIC_H)

This problem will be addressed in the next release; it turns out that
<asm/atomic.h> is a kernel header and user programs aren't supposed to use
it anyway.
