The existing documentation is at http://gcc.gnu.org/onlinedocs/gccint/Initialization.html and the following section http://gcc.gnu.org/onlinedocs/gccint/Macros-for-Initialization.html . In short, if use_collect2 is not set to yes in config.gcc, then collect2 will not generate a __main function. If use_collect2 is set to yes, but if you define LD_INIT_SWITCH, then collect2 will also not generate a call to a __main function. Ian
