You should write some startup code that runs all the constructors in .init_array, does any other required initialization, and then jumps to main. The program's entry point should be that startup code. You can name it anything you like; typical favorites are _init and _start. You may want to look at libgloss, which is parallel to newlib, for various examples. Ian
