【解决过程】
1.参考：
How can I build the Python Sybase module on Windows?
但是没太大帮助。
2.参考：
则去看看代码：
libxml2\libxml2-2.7.7\python\libxml.c
找到：
#include <Python.h>
再去找Python.h对应的：
cgwin中的 usr\include\python2.6\pyport.h
的：
/* On QNX 6, struct termio must be declared by including sys/termio.h if TCGETA, TCSETA, TCSETAW, or TCSETAF are used. sys/termio.h must be included before termios.h or it will generate an error. */ #ifdef HAVE_SYS_TERMIO_H #include <sys/termio.h> #endif
改为：
/* On QNX 6, struct termio must be declared by including sys/termio.h if TCGETA, TCSETA, TCSETAW, or TCSETAF are used. sys/termio.h must be included before termios.h or it will generate an error. */ #ifdef HAVE_SYS_TERMIO_H //#include <sys/termio.h> #include <termio.h> #endif
再去make编译试试，结果就可以继续编译了：

【总结】
cygwin下，交叉编译libxml2出现错误：
| /usr/include/python2.6/pyport.h:472:24: fatal error: sys/termio.h: No such file or directory |
的原因是：
libxml2-2.7.7\python\libxml.c
中包含了Python.h，对应在cygwin下，是：
usr\include\python2.6\pyport.h
其中原先是：
#ifdef HAVE_SYS_TERMIO_H #include <sys/termio.h> #endif
而由于旧的系统中的termio.h才是在/usr/include/sys中，新的系统，是在/usr/include中，所以，改为：
#ifdef HAVE_SYS_TERMIO_H //#include <sys/termio.h> #include <termio.h> #endif
就可以找到termio.h，即可解决问题。
