对于fcgi，我不管是用常规的 2.4.0版本，还是用最新的2.4.1(09年10月份发布的)，都是出现如下的错误：
root@localhost:~/downloads/fcgi-2.4.1-SNAP-0910052249# ./configure --prefix=/usr/local/fcgi-2.4.1
这一步没有问题。
接下来
root@localhost:~/downloads/fcgi-2.4.1-SNAP-0910052249# make
make all-recursive

我想这个fcgi开发一点也不活跃，而gcc的最新版本不断出来，很有可能是由于这方面引的原因，我又调整了一下关键字
gcc compile fcgi，(之前都是没有方向的搜索)。终于在第一条结果中找到原因了：http://bugs.gentoo.org/256654

Build of dev-libs/fcgi-2.4.1_pre0311112127 fails with the following errors:
fcgio.cpp: In destructor 'virtual fcgi_streambuf::~fcgi_streambuf()':

This is because #include <cstdio> is missing from one of the headers.
鉴于此：在解压包include/fcgio.h加入头文件#include<cstdio>，之后，编译将没有问题了。
编译fastcgi：gcc -lfcgi fcgi1.c -o fcgi1.fcgi
