+Subject: [PATCH 2/2] configure,rbldnsd.c: replace mallinfo() with mallinfo2()
+
+The mallinfo() function from malloc.h is deprecated, and has been
+replaced by mallinfo2(). Additionally, the "mallinfo" struct that it
+returns has been replaced by a "mallinfo2" struct. The only difference
+between the two is that the newer struct contains members of type
+size_t rather than int, which proved to be too small (leading to
+overflows).
+
+The call to ssprintf() that prints this information has been updated
+to use the "z" length modifier, which is C99, but which is probably
+safe by now. Other C99 features are already being used by rbldnsd.
