-* Need both binutils and GCC.

-* @@ This has been fixed, can go back to disabled NLS.
+* Use previous version of g++ to build the next (i.e., export PATH=/i686...).
 
-  Had to enable NLS (--enable-nls) for GCC 4.7.3. When disabled there
-  were some errors during plugin compilation in libintl.h (looked like
-  plugin headers assumed NLS is enabled while libstdc++ (locale) assumed
-  it was disabled so provided some dummy macros for gettext, etc.)
+* For some reason g++, cc1plus don't depend on dynamic libstdc++. If that
+  changes, then we will need to switch to the Mac OS way.
 
-TODO:
+* Cannot get 64-bit build of GCC to install into lib/. As a workaround,
+  pre-creating lib and lib64 as a link to it (this way, if we need to
+  rely on LD_LIBRARY_PATH setup in the driver, it will work).
 
-* Install plugin/gcc into lib64/ instead of lib/ for 64-bit binary.
+* Need both binutils and GCC.
