In the example above, the line "struct bar *getbar(int);" causes an incomplete
declaration of struct bar.  An earlier note complained about warning messages
from the HP ANSI C compiler.  However, in the example above, the HP ANSI C
compiler is silent because the incomplete declaration on the first line means
that the "struct bar" tag in the next line refers to "struct bar" at file
scope and not prototype scope.
