Why are you reinterpret_casting &t to itself? Is this a Borland problem as well?
Russell added the reinterpret_casts to my patch. Russell, can you comment?
And here is Russell's reply. Looks like it's necessary.
Truth is, I'm not sure why I reinterpret_cast t to its own type, but without it (i.e just return &t as Eric's original solution), FOREACH still gives these errors
[C++] main.cpp(1): [C++ Error] addressof.hpp(42): E2034 Cannot convert 'int *' to 'int ( *)[5]' [C++ Error] addressof.hpp(49): E2034 Cannot convert 'const int *' to 'int ( *) const[5]' As far as I can tell, the reinterpret_cast I've added isn't casting t to itself, as t is a T(&)[N], I'm reinterpret_casting it to the function return type, T(*)[N]. If this is incorrect, I can try other solutions if anyone has any suggestions, but just return &t doesn't work with bcc32-5.6.4. <<< -- Eric Niebler Boost Consulting www.boost-consulting.com
