From 2c75f8a612b207c7d36e5dc73317dc9ab6fb29d4 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 22 Mar 2021 11:20:44 -0400 Subject: [PATCH] Remove useless configure probe for . This seems to have been just copied-and-pasted from some other header checks. But our C code is entirely unprepared to support such a header name, so it's only wasting cycles to look for it. If we did need to support it, some #ifdefs would be required. (A quick trawl at codesearch.debian.net finds some packages that reference lz4/lz4.h; but they use *only* that spelling, and appear to be intending to reference their own copy rather than a system-level installation of liblz4. There's no evidence of freestanding installations that require this spelling.)
