I agree with Chris and Gedare. IMO: - Statics have no declarations but are ordered such that they are defined first in the source. This can be argued, some like to defer the definition arguing it puts unimportant details early in a file and so use static declarations. - System-wide externals are declared in system-wide header files; - Directory-local externals are declared in directory-local header files (not sure RTEMS layout likes that) or the directory is re-organized to be made statics (if possible without ballooning file size).
So: - externals are declared once, and only once, in a header. - objects are defined once, and only once, in a source.
