Alexey Dokuchaev 6b5eb98e6d Unbreak the build on 9.X (against old yacc(1) which apparently does not ... support %token_table declaration). Originally the port was relying on bison(1) instead (via USES=bison) in yacc-compat mode, but was switched to yacc(1) in r389653 because it failed to build against `devel/bison' version update to 3.0.4 as part of an exp-run (see PR). It turns out that actually generated code does not suffer from removing %token_table: the only difference in generated `neural_parse.cc' is that yyname[] table is not guarded by `#if YYDEBUG' and it #define's yytname as yyname, but the code that references yytname in `neural_parse.cc' is #if'ed 0 and YYDEBUG is defined to 1 earlier. That said, simply comment out %token_table line which allows the build to proceed (ir)regardless of the yacc(1) version, on all FreeBSD releases (including 8.X). While here, remove `ac_cv_lib_stdcpp_main=no' in CONFIGURE_ENV that was supposed to fix the build against Clang added in r323095 as it seems no longer required, augment COMMENT and port description, and fix WWW line to point to working website, killing trailing whitespace along the way.
