Bug#177041: g++-3.2: bison output not compilable with g++-3.2 due to __atttribute__((__unused__))

Package: g++-3.2
Version: 1:3.2.2-0pre5
Severity: normal
Tags: upstream

Occasionally it is useful to compile the output of bison with C++.
However, bison output contains the following lines:

>  /* Suppress GCC warning that yyerrlab1 is unused when no action
>       invokes YYERROR.  */
>#if defined (__GNUC_MINOR__) && 2093 <= (__GNUC__ * 1000 + __GNUC_MINOR__)
>  __attribute__ ((__unused__))
This compiles fine with gcc, but with g++ the error

> parse error before `goto'

is given.  I believe that earlier versions of g++-3.2, and certainly
earlier versions of g++, compiled this code with no problems.
