Chuck, Now that gcc4 has been promoted to the default compiler on 1.7, libtool requires a rebuild so that sys_lib_search_path_spec in /usr/bin/libtool points to the correct directory (/usr/lib/gcc/i686-pc-cygwin/4.3.4 vs. 3.4.4). This will be necessary each time gcc4 gets a version bump (but multiple releases of the same version don't matter).
