[ECOS] mix use between C++ and C in eCOS. Thanks

[QiangHuang]

Hi all:
    I got the a question:

//========================================================
c_file.h

void test_fun(void);
//========================================================

//========================================================
c_file.c

void test_fun(void)
{
  //do something here
}
//========================================================

//========================================================
cplusplus_file.hxx

#include <c_file.h>
//========================================================


//========================================================
cplusplus_file.cxx

void myfun(void)
{
   // do something here

   // call the function defined in the C file
   test_fun();
}
//=========================================================


I can build the eCOS library without problem but when I link my application
with the library I got the problem: "undefined reference to test_fun()"

I think this should be a C/C++ linkage problem, but I don't have clue. Can
anybody give me help on this issue? Thanks a lot.
