Java JNI C 程序适用于 Mingw32，但不适用于 Cygwin64

Question

下面给出的 Java JNI 程序在环境 (1) 中运行良好。但如果我将环境更改为(2)，则会出现错误。感谢任何帮助解决此错误的帮助。

Java 代码:

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 代码 (.c)

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

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

运行良好的环境 (1):
操作系统:Windows 8.1 64位
Java jdk1.8.0_51(32位)
Mingw 32位
C 编译器选项:-shared -m32 -Wl,--add-stdcall-alias
Netbeans 使用 32 位 Java 运行

出现错误的环境(2):
操作系统:Windows 8.1 64位
Java jdk1.8.0_51(64位)
CYGWIN 64 位
没有编译器选项
将“C:\cygwin64\bin”添加到路径环境变量
Netbeans 使用 64 位 Java 运行

错误:
