// APP_ENTRY_POINT
//
// Defines the application entry point function, if undefined this setting
// defaults to "main".
//
// INITIALIZE_STACK
//
// If defined, the contents of the stack will be initialized to a the
// value 0xCC.
//
// INITIALIZE_SECONDARY_SECTIONS
//
// If defined, the .data2, .text2, .rodata2 and .bss2 sections will be initialized.
//
// INITIALIZE_TCM_SECTIONS
//
// If defined, the .data_tcm, .text_tcm, .rodata_tcm and .bss_tcm sections
// will be initialized.
//
// INITIALIZE_USER_SECTIONS
//
// If defined, the function InitializeUserMemorySections will be called prior
// to entering main in order to allow the user to initialize any user defined
// memory sections.
//
// FULL_LIBRARY
//
// If defined then
// - argc, argv are setup by the debug_getargs.
// - the exit symbol is defined and executes on return from main.
// - the exit symbol calls destructors, atexit functions and then debug_exit.
//
// If not defined then
// - argc and argv are zero.
// - the exit symbol is defined, executes on return from main and loops
