Cygwin Compile Error in AppDelegate.h

cocos2d-x C++
#1

I include Server.h into AppDelegate.h header. When i use cgywin to compile it, it shows some errror messages.
But i include Server.h into AppDelegate.cpp. Then compile sucessfully.

Can anyone help me?

Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := game_logic_static
LOCAL_MODULE_FILENAME := libgame_logic
LOCAL_SRC_FILES := AppDelegate.cpp Server.cpp
LOCAL_C_INCLUDES := $(LOCAL_PATH)
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)
LOCAL_STATIC_LIBRARIES := png_static_prebuilt
LOCAL_STATIC_LIBRARIES = xml2_static_prebuilt
LOCAL_STATIC_LIBRARIES= jpeg_static_prebuilt
LOCAL_WHOLE_STATIC_LIBRARIES += cocos2dx_static
LOCAL_SHARED_LIBRARIES := cocosdenshion_shared

include $(BUILD_STATIC_LIBRARY)
$(call import-module,cocos2dx/platform/third_party/android/modules/libpng)
$(call import-module,cocos2dx/platform/third_party/android/modules/libxml2)
$(call import-module,cocos2dx/platform/third_party/android/modules/libjpeg)

Thanks you.
