cyrus-sasl2 trips over C23 because its md5 code still defaults to no prototypes because this feature is way to modern for such a critical piece of software.
In C23 a prototype of static void MD5_memcpy () is equal to static void MD5_memcpy (void) which is not what we want. -- :wq Claudio Index: patches/patch-include_makemd5_c =================================================================== RCS file: patches/patch-include_makemd5_c diff -N patches/patch-include_makemd5_c --- /dev/null 1 Jan 1970 00:00:00 -0000 +++ patches/patch-include_makemd5_c 17 Nov 2025 14:08:08 -0000 @@ -0,0 +1,19 @@ +Enable PROTOTYPES by default, even base-gcc handles this modern feature. + +Index: include/makemd5.c +--- include/makemd5.c.orig ++++ include/makemd5.c +@@ -155,11 +155,11 @@ static int print_pre(FILE *f) + "\n" + "/* PROTOTYPES should be set to one if and only if the compiler supports\n" + " function argument prototyping.\n" +- "The following makes PROTOTYPES default to 0 if it has not already\n" ++ "The following makes PROTOTYPES default to 1 if it has not already\n" + " been defined with C compiler flags.\n" + " */\n" + "#ifndef PROTOTYPES\n" +- "#define PROTOTYPES 0\n" ++ "#define PROTOTYPES 1\n" + "#endif\n" + "\n" + "/* POINTER defines a generic pointer type */\n"
