No matter how we do this, we'd need to maintain that list, so the
choices are between "#define" and "objcopy --redefine-sym" if we
limit ourselves to static linking, I think. The former may be more
portable but makes me feel dirty. The debuggers will not see the
names we want to use, for one thing. "rename selected symbols in *.o
files" approach, if it can be done on platforms we want the lib thing
on, would be more preferable.
We also should be able to create a single linkable object (e.g., Z.o
out of X.o and Y.o from the previous example---it could be Z.so that
is dynamically linked at runtime) to resolve the symbols that need
to be shared only among the object files (like "foo" that is defined
in X.o whose address is needed in Y.o) and after such a linking is
done, these "internal" symbols can be stripped away from the
resulting object file. For that, we'd also need to maintain that
list of internal symbols that are needed in order to link our
objects together.
