/* This external variable can be set by any debugger to flag to the runtime
that we are currently executing inside a debugger. This will allow the
debugger to override the number of threads spawned in a parallel region by
using __kmp_omp_num_threads() (below).
* When __kmp_debugging is TRUE, each team and each task gets a unique integer
identifier that can be used by debugger to conveniently identify teams and
tasks.
* The debugger has access to __kmp_omp_debug_struct_info which contains
information about the OpenMP library's important internal structures. This
access will allow the debugger to read detailed information from the typical
OpenMP constructs (teams, threads, tasking, etc. ) during a debugging
session and offer detailed and useful information which the user can probe
about the OpenMP portion of their code. */

threads can be changed at the debugger's request. */
