[section:portability Portability]

A huge effort has been made to port the library to as many compilers as possible.

Full support for built-in arrays require that the compiler supports class template partial specialization. For non-conforming compilers there might be a chance that it works anyway thanks to workarounds in the type traits library.
Visual C++ 6/7.0 has a limited support for arrays: as long as the arrays are of built-in type it should work.

Notice also that some compilers cannot do function template ordering properly. In that case one must rely of __range_iterator__ and a single function definition instead of overloaded versions for const and non-const arguments. So if one cares about old compilers, one should not pass rvalues to the functions.

For maximum portability you should follow these guidelines:

# do not use built-in arrays,
# do not pass rvalues to __begin__`()`, __end__`()` and __iterator_range__ Range constructors and assignment operators,
# use __const_begin__`()` and __const_end__`()` whenever your code by intention is read-only; this will also solve most rvalue problems,
# do not rely on ADL:
  * if you overload functions, include that header before the headers in this library,
  * put all overloads in namespace boost.
