+Subject: [PATCH] sgmls-1.1: fix configure script with Clang 16
+
+Clang 16 makes -Wimplicit-function-declaration and -Wimplicit-int errors by default.
+
+Unfortunately, this can lead to misconfiguration or miscompilation of software as configure
+tests may then return the wrong result. In this case, it led to a build failure
+(see https://bugs.gentoo.org/883203).
+
+We also fix -Wstrict-prototypes while here as it's easy to do and it prepares
+us for C23.
+
+For more information, see LWN.net [0] or LLVM's Discourse [1], the Gentoo wiki [2],
+or the (new) c-std-porting mailing list [3].
