Java JNI C程序可以與Mingw32一起正常運行，而不能與Cygwin64一起運行

Question

下面給出的Java JNI程序在環境下可以正常使用（1）。 但是，如果我將環境更改為（2），則會出錯。 感謝您提供幫助以解決此錯誤。

Java代碼：

package avajjni;
public class AvajJNI {
    static{
    //Environment (1)
    //System.load("D:\\cpro\\c_jni_library\\dist\\Debug\\MinGW_32-Windows\\libc_jni_library.dll");

    //Environment (2)
    System.load("D:/cpro/c_jni_library/dist/Debug/Cygwin_64-Windows/libc_jni_library.dll");
    }
    public native void fnDisplayData();
    public static void main(String[] args) {
        AvajJNI obj = new AvajJNI();
        obj.fnDisplayData();
    }
}

C代碼（.c）

#include <stdio.h>
#include "avajjni_AvajJNI.h"

JNIEXPORT void JNICALL Java_avajjni_AvajJNI_fnDisplayData
  (JNIEnv *env, jobject obj){
    printf("JNI Method Called\n");
}

工作環境良好的環境（1）：
操作系統：Windows 8.1 64 bit
Java jdk1.8.0_51（32位）
Mingw 32位
C編譯器選項：-shared -m32 -Wl，-add-stdcall-alias
Netbeans使用32位Java運行

產生錯誤的環境（2）：
操作系統：Windows 8.1 64 bit
Java jdk1.8.0_51（64位）
Cygwin 64位
沒有編譯器選項
將“ C：\\ cygwin64 \\ bin”添加到路徑環境變量
Netbeans使用64位Java運行

錯誤：
