+Subject: [PATCH] Fix extra reference of parameters of rrd_fetch_dbi_{long,double}
+Upstream: https://github.com/oetiker/rrdtool-1.x/pull/1255
+Refrences: boo#1225919
+
+Functions rrd_fetch_dbi_long and rrd_fetch_dbi_double currently take
+the first parameter of type "bi_result result *" even though that is
+already a pointer and the use of that parameter suggests the extra
+indirection is not wanted.  What is more, the caller passes just
+"bi_result result" to the corresponding actual arguments which results
+in compile errors with GCC 14 because it now does not accept
+incompatible pointer types by default.
