I take it all conflicts not involved in error recovery have been examined
in the Bison dumps to ensure they aren't resolved incorrectly?  (The prior
state should have been - was at one stage - that there was exactly one
such conflict, in __attribute__((foo(bar))) and similar, where the 
identifier "bar" starting arguments to an attribute is interpreted as an 
identifier in preference to an expression in an exprlist.)
