    Microsoft C, surprisingly enough, handles this correctly, while
 pcc's cpp ignores the // so that

 #define	RDR 1    // reader

   x = y[RDR] ;

 is expanded to

   x = y[1   // reader]

 resulting in a very frustrating source of error messages from cfront.
 This is a problem with most implementations of cfront that dont supply
 their own cpp and even with a few that do. 

 ( the LPI c compiler, which claims to be ANSI, ignores _//_, and barfs at 
 things like _#ident_ and most everything else )
