'::text_output' is an enumerator.

'Diagnostics::text_output' is a member function.

Which 'text_output'?

A later gcc version gives:
  In file included from DiagnosticsTest.cpp:6:
  Diagnostics.hpp:29: error: default argument for 'output_mode_type o_mode'
  has type '<unresolved overloaded function type>'

To confirm that the code is erroneous, use
  http://www.comeaucomputing.com/tryitout/
which will tell you about some other problems that
'g++ -W -Wall -std=c++98 -pedantic' would report as well.

To fix the reported error:
- inline Diagnostics::Diagnostics(output_mode_type o_mode=text_output):
+ inline Diagnostics::Diagnostics(output_mode_type o_mode=::text_output):
                                                          ^^
