[C] Demonstrates how to use extended severity information, via PANTHEIOS_MAKE_EXTENDED_SEVERITY().

/* /////////////////////////////////////////////////////////////////////////
 * File:        examples/c/example.c.extended_severity/example.c.extended_severity.c
 *
 * Purpose:     C example program for Pantheios. Demonstrates:
 *
 *                - how the Pantheios libraries must be explicitly
 *                  initialised in a C program; this is not the case in
 *                  C++ programs
 *                - use of extended severity information, via
 *                  PANTHEIOS_MAKE_EXTENDED_SEVERITY()
