//
// File defining fields in the Yap_GLOBAL global structure
//
// these fields used to spread all over the place, because they must be used in 3 ways:
// - they must be defined somewhere
// - they have an #ifdef to get a shorter name
// - they must be initialised somewhere
// - they may be of interest to restore
//
// The defs include 4+ components:
// Type
// name in structured
// global name
// init code (optional)
// restore code (optional)
//
// Stuff that must be shared by all threads or workers
START_GLOBAL_DATA
// initialization: tell whether the system has been initialised and by whom.
