bison 1.875 exits on compiling objc-parse.y complaining that there are reduce/reduce conflicts where none were expected.

This is a recent change, but it is an extension of the behaviour documented in the Bison 1.28 info documentation.  According to the Bison 1.28 documentation, 

     %expect N

   Here N is a decimal integer.  The declaration says there 
   should be no warning if there are N shift/reduce 
   conflicts and no reduce/reduce conflicts.  The usual 
   warning is given if there are either more or fewer 
   conflicts, or if there are any reduce/reduce conflicts.

Bison 1.875 has converted the warning to an error in those exceptional cirumstances.

%expect was misused in objc-parse.y.  Removing it should not result in more warnings than already there, and also prevents errors when using a newer bison.

Release:
gcc-3.4

Environment:
i686-pc-linux-gnu
