+Subject: [PATCH] acinclude.m4: Add parameter names in prototype for g().
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This allows it to compile with older gcc e.g. gcc-10
+which does not have allow parameter name omission, it results
+in
+
+a.c: In function ‘g’:
+a.c:3:8: error: parameter name omitted
+    3 | void g(int,t1 const*,t1,t2,t1 const*,int){}
+      |        ^~~
+
+this was added to gcc via [1] thats why it is supported in
+newer gcc.
+
+Adding the parameter names make it compatible with
+old and new gcc
