The only source changes made are to disable includes for headers not referenced in the build, and this:
+/* LIBBITCOIN: fix warning when WIN32_LEAN_AND_MEAN is already defined. */
+#ifndef WIN32_LEAN_AND_MEAN
#define WIN32_LEAN_AND_MEAN
+#endifThe in-place change allows for and easy source diff against the previous version. However wolf did refactor some large files into smaller ones, so there are a number of additions (no removals).
