This is already fixed as 4.2.1-7. The new automake differs from the previous one and causes some wierdness in ac_fn_cxx_try_link, causing icu's configure to think that there is no namespace support in g++. Hacking in a toplevel AC_LANG_PUSH([C++]) AC_LINK_IFELSE([AC_LANG_PROGRAM()]) AC_LANG_POP([C++]) works around it.
Checked in in upstream, and updated ICU configure to autoconf 2.67. Targetted for ICU 4.6, thanks.
