Bug #3393: (libc) catopen(3): align returned errors with IEEE Std 1003.1™-2024
http://bugs.dragonflybsd.org/issues/3393#change-14790

* Author: pmjdebruijn
* Status: Resolved
* Priority: Low
* Category: Userland
* Target version: 6.6
* Start date: 2026-01-22
----------------------------------------
Ref: https://reviews.freebsd.org/D47413

* Invalid/non-existent/unable to use message catalog file should result in ENOENT, and not in EFTYPE.
* Added detection of several cases of wrong file format due to length [*].
* Update man page.

Patch: https://cgit.freebsd.org/src/patch/lib/libc/nls/msgcat.c?id=1176390d2d2bbb1e207c840d1f7a66a6ac1096ff (patch (with fuzz) applies and compiles)

There are some other "upstream changes" to the nls code as well, so cherry-picking this patch vs syncing the nls codebase is a tradeoff probably worth considering...
