I know that the compiler is invoked for every separate c file so it will include say function _delay() in every .c file. The linker then puts all the objects together and makes the binary but does it strip the duplicate _delays?? I know the pragma once and other inclusion guards are only relative to that source file being compiled and each source will include the functions.

declared in my header and want to use these states in multiple source files so I include the header when I need it. I also have an initialized structure struct branch the_table[8][5] = { {Control,0,0,0,0,0}, {Speed,0,0,0,0,0} }; and since this structure is using memory I must put it in my source file the problem is I want to be able to access this array outside of its source file and if I declare extern truct branch the_table[8][5]; in the header with the rest of the structure decelerations other source files cannot access its internal structure.
