The branch main has been updated by ngie: URL: https://cgit.FreeBSD.org/src/commit/?id=db5344a7445f1a796bc3cacd32a46e88e3e589a7 commit db5344a7445f1a796bc3cacd32a46e88e3e589a7 Author: Enji Cooper <ngie@FreeBSD.org> AuthorDate: 2026-02-26 02:29:49 +0000 Commit: Enji Cooper <ngie@FreeBSD.org> CommitDate: 2026-02-26 07:41:08 +0000 lib/libnetbsd: bring in `__type_m{ax,in}*` macro family These macros are used by some of the NetBSD tests which calculate the size of types, e.g., `__type_max(time_t)`. This wraps up the set of macros needed in order to update to the a netbsd-tests snapshot from this past month.
