Only one of each external function or variable name, and library member is
generally an individual .o file.  The reason to put only one external
function in each .o is that linkers generally can only shed unwanted
baggage at the level of individual .o files, and therefore if something in
a .o file is needed, the whole file will be linked in.  This guideline is
therefore intended to minimize the size of statically linked binaries by
giving the linker maximum freedom to drop unused code.
