   Note: The value of the symbol defined in the END_RELOC_NUMBERS
 
   macro (R_foo_count in the case of the example above) will be
 
   set to the value of the whichever *_RELOC macro preceeds it plus
 
   one.  Therefore if you intend to use the symbol as a sentinel for
 
   the highest valid macro value you should make sure that the
 
   preceeding *_RELOC macro is the highest valid number.  ie a
 
   declaration like this:
 
 
 
        START_RELOC_NUMBERS (foo)
 
            RELOC_NUMBER (R_foo_NONE,    0)
 
            RELOC_NUMBER (R_foo_32,      1)
 
            FAKE_RELOC   (R_foo_illegal, 9)
 
            FAKE_RELOC   (R_foo_synonym, 0)
 
        END_RELOC_NUMBERS (R_foo_count)
 
 
 
   will result in R_foo_count having a value of 1 (R_foo_synonym + 1)
 
   rather than 10 or 2 as might be expected.
 
 
 
   Alternatively you can assign a value to END_RELOC_NUMBERS symbol
 
   explicitly, like this:
 
 
 
        START_RELOC_NUMBERS (foo)
 
            RELOC_NUMBER (R_foo_NONE,    0)
 
            RELOC_NUMBER (R_foo_32,      1)
 
            FAKE_RELOC   (R_foo_illegal, 9)
 
            FAKE_RELOC   (R_foo_synonym, 0)
 
        END_RELOC_NUMBERS (R_foo_count = 2)
