From 8fab4b34801331f1c59352cb0a248be436b60aef Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 17 Jul 2023 16:54:54 -0400 Subject: [PATCH] Include in fe-auth.c, to get CHAR_BIT reliably. fe-auth.c references CHAR_BIT since commit 3a465cc67, but it did not #include , which per POSIX is where that symbol is defined. This escaped notice so far because (a) on most platforms, pulls in , (b) even if yours doesn't, OpenSSL pulls it in, so compiling with --with-openssl masks the omission. Per bug #18026 from Marcel Hofstetter. Back-patch to v16.
