解決方案是安裝或升級re2c 0.13.4以上版本。
下面我們用rpm包安裝此庫。
centos-5 32位：http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el5.rf.i386.rpm
centos-5 64位：http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el5.rf.x86_64.rpm
centos-6 32位：http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el6.rf.i686.rpm
centos-6 64位：http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el6.rf.x86_64.rpm
configure: error: pthreads requires ZTS, please re-compile PHP with ZTS enabled
原因： 我在編譯php的時候沒有加入 --enable-maintainer-zts ，這個必須要重新編譯php，不能動態載入的！
於是我重新編譯了php，在原來的編譯參數基礎上那個加入了 --enable-maintainer-zts ，重新編譯安裝php即可！
以下為一個樣本
