///////////////////// Tasking/Sleep/Timing options ///////////////////
//
// There are 4 options available
// (1) Tasking/Sleeping thru DLLSCHED: #defs reqd are !TSK !TMR and !IFK
// (2) Tasking/Sleeping thru an IFKERNEL BGproc: #defs reqd TSK IFK and !TMR
// (3) Tasking thru WIN32: #defs reqd WIN32 !IFK !TMR
//
//      In this file we define the macros for each of these options
