I think it is. ANSI C99 says this about linkage:
 6.2.2 Linkages of identifiers
 1 - An identifier declared in different scopes or in the same scope
 more than once can be made to refer to the same object or function by
 a process called linkage.(21)
 (21) THERE IS NO LINKAGE BETWEEN DIFFERENT IDENTIFIERS.
