   Probably not. You've created circular definitions of foo and bar with the
   preprocessor. ("foo" expands to "xyz.foo" which expands to "xyz.xyz.foo"
   ad infinitum.)

Only in some compilers.  ANSI C, most notably, disables expansion of
the macro name being defined in the body of the definition, as well as
in the expansion of macroes used in the definition.  Very handy.
