The gcc prereq page says gettext 0.14.5 is the minimum version, but po/zh_TW.po has lines like this:
#, fuzzy #~| msgid "Unexpected EOF" #~ msgid "Unexpected type..." #~ msgstr "未預期的型態…" The | syntax appears to have been added in gettext 0.16, and gettext 0.14 can't process it. Seems to have been a result of this request: http://gcc.gnu.org/ml/gcc-patches/2013-06/msg01436.html
