Since PostgreSQL 9.3, in commit a266f7dd93b, we've added the text: + The obsolete "winflex" binaries distributed on the PostgreSQL FTP site + and referenced in older documentation will fail with "flex: fatal + internal error, exec failed" on 64-bit Windows hosts. Use flex from + msys instead.
At this point. I suggest we simply stop distributing winflex on our download site, and just remove this note from the documentation. (This is just a note, the general documentation still says get flex from msys, separately). Surely a binary that doesn't work on a 64-bit system is not of help to anybody these days.. And "older documentation" now refers to 9.2 which was EOL in 2017. -- Magnus Hagander Me: https://www.hagander.net/ Work: https://www.redpill-linpro.com/
