Hello,

today I started to use NASM and djgpp together and soon encountered the
following problem:

The code of the assembly file is about like this:

BITS 32
GLOBAL _test
SECTION .text
_test: push ebp
           mov ebp, esp
           pop ebp
           ret
SECTION .data
GLOBAL _Mist
_Mist: dd 0xdeadbeef

In C++ I wrote something like that:

extern void test(void);
extern unsigned int Mist;
...
...
test();
cout << '\n' << hex << Mist;

Several times I tried to "build all", removed and added again all that
underbars in front of the function names, but the effect was every time,
that "Mist" worked very well, but "test()" caused the nasty error message
"undefined reference to test(void)".

What have I done wrong?
