+- Replaced include/share/alloc.h with a new file.
+- include/libFLAC/private/macros.h: don't conditionalize on GCC version >= 4.3;
+  Clang looks like GCC 4.2, but we want these defines.
+- src/share/win_utf8_io/win_utf8_io.c: call LoadLibraryA instead of just
+  LoadLibrary since the argument is a non-wide string.
