: Does it mean that subsets of an enum cannot be defined ?

  Yes.  K&RvII, pg 215:  

  "Enumerations are unique types with values ranging over
a set of named constants called enumerators...  Enumerator
names in the same scope must all be distinct from each
other and from ordinary variable names, but the values
need not be distinct."

: Is this a bug in my C Compiler ?

  No.

: Is there a work around ?

  Of course ;-)
