+Subject: linuxthreads.new: initialize stdio locking
+
+uClibc requires the threading library to enable locking for
+stdio, or the locking is not done at all.

+Subject: malloc-simple: Make calloc() return zeroed memory
+
+The 0.9.31 release included a change to malloc-simple to request
+uninitialized memory from noMMU kernels. Unfortunately, the corresponding
+calloc() code assumed that memory returned by malloc() was already zeroed,
+which leads to all kinds of nastiness.

+Subject: Fix ctime() standard compliance bug
+
+fixes issue2209:
+ctime() was updated in 0.9.31 to call localtime_r() instead of
+localtime() to
+avoid using a static buffer. Unfortunately, this change replaces the
+static
+buffer (which is zeroed out on initialization) with an uninitialized
+local
+buffer.
+
+In the common case, this has no effect. However, with a sufficiently
+large
+time_t value, the value returned differs from that returned by
+asctime(localtime(t)), and thus violates the ANSI/ISO standard.
+
+An example input is (on a 64-bit machine):
+time_t t = 0x7ffffffffff6c600;
