19 | * This is much trickier than it looks. We are #include'ing kwlist.h |
20 | * but the token numbers that go into the table are from preproc.h |
21 | * not the backend's gram.h. Therefore this token table will match |
22 | * the ScanKeywords table supplied from common/keywords.c, including all |
23 | * keywords known to the backend, but it will supply the token numbers used |
24 | * by ecpg's grammar, which is what we need. The ecpg grammar must |
25 | * define all the same token names the backend does, else we'll get |
26 | * undefined-symbol failures in this compile. |
