Hi,

I have a test1.lib created by the microsoft visual c++ compiler.
test1.lib contains only one function test1(), which prints out "Hello from 
test1".

The other file I have is main.c, which prints out "Call Test1", call test1
() and prints out "Return Test1".

---------------------------------------------------------------------------

/* test1.c */

#include <stdio.h>
__declspec(dllexport)
void test1(void) {
    printf("Hello from test1()\n");
}

---------------------------------------------------------------------------

#Makefile for creating test1.lib

target: test1.dll
test1.dll:
    cl -c /MD test1.c
    link /out:test1.dll /DLL test1.obj
clean:
    rm -rf test1.dll test1.obj test1.lib

---------------------------------------------------------------------------

/* main.c */

#include <stdio.h>
int main() {
    printf("Call Test1\n");
    test1();
    printf("Return Test1\n");
    return 0;
}

---------------------------------------------------------------------------

#Makefile for creating main.exe in cygwin using mingw libraries and headers

target: main.exe
main.exe: main.o test1.lib
    gcc -mno-cygwin -o main.exe main.o test1.lib
main.o: main.c
    gcc -mno-cygwin -c main.c
clean:
    rm -rf main.exe *.o

---------------------------------------------------------------------------

output: 

$ ./main.exe
Call Test1
Return Test1
Hello from test1()

---------------------------------------------------------------------------

"Hello from test1()" should be between "Call Test1" and "Return Test1".

In the first makefile, I use /MD option to link with MSVCRT.LIB. But in 
the second makefile used in cygwin, I have no idea how to correctly link 
with MSVCRT.LIB using gcc -mno-cygwin.

So, is that the reason why the output order is incorrect?
And how to link with MSVCRT.LIB correctly in cygwin using gcc or gcc -mno-
cygwin?

Thanks
