aclocal的bug

今天学习一下automake，但是在运行aclocal的时候会右警告：
/usr/share/aclocal/libstroke.m4:29: warning: underquoted definition of smr_ARG_WITHLIB/usr/share/aclocal/libstroke.m4:29:   run info '(automake)Extending aclocal'/usr/share/aclocal/libstroke.m4:29:   or see www.2cto.com
上网搜了一下，这似乎是一个很老的bug，并且很早就有了patch，但是搞不懂为什么在Debian中依然存在?
