Hi Rob,
I have uploaded what I believe to be a corrected version of istream_range. I have to confess that I have not yet been able to check this on a GCC compiler, but I think I simply had two template parameter types switched. My test case was using 'char' for both 'Type' and 'Elem' hence I did not detect the issue.
I am installing Xcode as we speak on a Mac so I will in due course find out if this works on GCC. Since the change did not make things any worse I have posted it anyhow.
Hi Neil Thanks for that - that now works for me! However, (sorry!), the next step, using adaptors, fails when I only include the adaptors header file.
