我想尝试在cygwin上脱皮。
shed skin和libgc的安装似乎没问题，但是当我尝试make使用 shed-skinned Python 脚本时，它会抱怨：
/usr/lib/python2.7/site-packages/shedskin/lib/builtin.hpp:31:22: fatal error: execinfo.h: No such file or directory
compilation terminated.
（下面的完整列表）
我在 Cygwin 上检查了 libgc 的已安装文件列表，它不包括execinfo.h
这是否意味着脱落的皮肤不能在Cygwin上使用？

编辑1：
将缺少的execinfo.h（从 Internet下载）添加到 make 的 lib 路径没有帮助。
$ shedskin -L `pwd` shedskinfn.py && make
