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:
iterator_rangeRange constructors and assignment operators,
()whenever your code by intention is read-only; this will also solve most rvalue problems,
do not rely on ADL:
