commit 80e3a8b5c6850f1f294b0e7a0aad36a0e8a8d1c7 Author: Tom Jones <[email protected]> AuthorDate: 2022-01-27 17:24:45 +0000 Commit: Dag-Erling Smørgrav <[email protected]> CommitDate: 2024-01-17 15:52:02 +0000 Remove SMALL conditionals from gzip gzip has SMALL conditionals which enable building a reduced size version of the binary. These exist as part of the introduction of BSD licensed gzip in 2004 in NetBSD and appear to have been required to reach a size for inclusion in their install media. For more information see commits to gzip in the NetBSD tree on the 28th of March 2004. SMALL doesn't appear to be hooked up to our build system and complicates gzip quite a bit.
