Except that inline asm is also used, so they must agree.

The former provides a tentative definition of g which will avoid
pulling in other .o files from an archive (.a) to satisfy references
to g, but which allows another .o file which defines g to override the
tentative definition.

The latter provides a full definition of g which will result in link
errors if g is defined elsewhere.
