+Subject: [PATCH] Add #include <algorithm> to fix building with gcc 14 (#20981)
+
+With gcc 14 some C++ Standard Library headers have been changed to no
+longer include other headers that were used internally by the library.
+In OpenRCT2's case it is the <algorithm> header.
+
+Downstream Gentoo bug: https://bugs.gentoo.org/917016
+
+GCC 14 porting guide: https://gcc.gnu.org/gcc-14/porting_to.html#header-dep-changes
