# 这里生成 jvm.dll
# jdk/bin/zip.dll 和 jdk/bin/java.dll 均依赖此dll
# 如果加载以上两个dll失败，可以用‘Dependency Walker’之类的工具查看下这两个dll所依赖的函数在jvm.dll中是否实现。
# 如果有函数没有实现，可以在jvm.cpp中实现之。
# 如果有Debug加载zip.dll和java.dll成功，而Release版失败的情况，可以考虑下是不是Release版是不是把jvm.cpp中没有使用的函数优化掉了。
# 总之一句话，无论Debug版还是Release版jvm.dll中导出所有zip.dll和java.dll中所依赖的函数。
