template bug

[Martin v. Loewis]

> g++ should be able to resolve the call to the overloaded function:

Thanks for your bug report. This is not a bug in the compiler, but in
your code. Both candidates are viable, they require the same
conversion sequences on arguments, and neither is as specialized as
the other.

If you question this line of reasoning, please discuss it in one of
the public C++ fora first, eg. comp.lang.c++.moderated, or
comp.std.c++.

Regards,
Martin
