編譯最新的2.0.35版本，用默認的 ./configure編譯
當make的時候，出現以下錯誤
configure.ac:64: error: possibly undefined macro: AM_ICONV
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
make: *** [configure] Error 1
解決辦法 ，編譯加m4_pattern_allow參數
即：./configure --enable-m4_pattern_allow
便能順利編譯安裝
