HPC_DEBUG_COMPAT Environment Variable
HP C does not emit debug information for unused objects (structures, unions, and others)
anymore with the -g option. For getting the older behavior (emitting debug information for all
objects, irrespective of whether they are used in the program or not), the environment
variable HPC_DEBUG_COMPAT can be set in the environment along with the -g option in the
compilation command line. It suffices to define this environment variable to have an empty
string; it does not need to be set to any particular value.
