Changes in version 1.49a:
* False `Token not used' report fixed.
On a grammar such as
%token useless useful
%%
exp: '0' %prec useful;
where a token was used to set the precedence of the last rule,
bison reported both `useful' and `useless' as useless tokens.
* Revert the C++ namespace changes introduced in 1.31, as they caused too
many portability hassles.
