+Subject: [PATCH] addrdb/coord-config-parse.y: add missing <time.h> include
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The %union definition uses the time_t structure. In order to use this
+structure, the <time.h> header has to be included. Otherwise, the build
+breaks with some C libraries, such as musl:
+
+In file included from coord-config-lex.l:23:0:
+coord-config-parse.y:107:2: error: unknown type name ‘time_t’
+  time_t timestamp;
+  ^
+
+This patch includes <time.h> using the '%code requires' directive of
+Yacc.
