init code

[dreese@vandals.uidaho.edu]

Does gcc currently posses the functionality to do the following?

I would like to have gcc compile in a function that initializes a global variable into the target programs memory space. I need this initialization function to be called before any code is executed from the target program. I need to have gcc do this for every program that it compiles with out being asked. 

Does anyone have any ideas?

Thanks for your time.
