Index: ChangeLog
from Akim Demaille <address@hidden>
Remove `%thong' support as it is undocumented, unused, duplicates
`%token's job, and creates useless e-mail traffic with people who
want to know what it is, why it is undocumented, unused, and
duplicates `%token's job.
* src/reader.c (parse_thong_decl): Remove.
* src/options.c (option_table): Remove "thong".
* src/lex.h (tok_thong): Remove.

-| Parse what comes after %thong. the full syntax is |
-| |
-| %thong <type> token number literal |
-| |
-| the <type> or number may be omitted. The number specifies the |
-| user_token_number. |
-| |
-| Two symbols are entered in the table, one for the token symbol and |
-| one for the literal. Both are given the <type>, if any, from the |
-| declaration. The ->user_token_number of the first is |
-| USER_NUMBER_ALIAS and the ->user_token_number of the second is set |
-| to the number, if any, from the declaration. The two symbols are |
-| linked via pointers in their ->alias fields. |
-| |
-| During OUTPUT_DEFINES_TABLE, the symbol is reported thereafter, |
-| only the literal string is retained it is the literal string that |
-| is output to yytname |
