+    - Fixes Autotools determination of the stat struct having an st_blocks field
+
+      A missing parenthesis in an autoconf macro prevented building the test
+      code used to determine if the stat struct contains the st_blocks field.
+      Now that the test functions correctly, the H5_HAVE_STAT_ST_BLOCKS #define
+      found in H5pubconf.h will be defined correctly on both the Autotools and
+      CMake. This #define is only used in the tests and does not affect the
+      HDF5 C library.
