Boost :

John Maddock's suggested ABI clash prevention wrapper code looks like this
for the prefix:

   #include <boost/config.hpp>

   // this must occur after all of the includes and before any code
   # include BOOST_ABI_PREFIX

and for the suffix:

   // the suffix header occurs after all of our code:
   # include BOOST_ABI_SUFFIX

That approach avoids including the BOOST_ABI_PREFIX/BOOST_ABI_SUFFIX
headers if they would be empty anyhow (because the compiler has no ABI

It does, however, clutter up the source code.

It would be possible avoid some of that clutter by supplying two additional
headers, say <boost/abi_prefix.hpp> and <boost/abi_suffix.hpp>. The
contents would essentially be the two respective code snippets about.

Usage would simply be:

   #include <boost/abi_prefix.hpp> // after all other includes
   #include <boost/abi_suffix.hpp> // after all code

Note that these additional headers don't have to be used. A Boost developer
would still be free choose the lengthier form above if that suited her
preferences. The two forms are functionally equivalent.
