undefined symbols in dlls?

[vikramshrowty@yahoo.com]

Hi,
	Aren't dlls alowed to  have undefined symbols?
--------------
foo.c:

int bar();

int foo() {
  return bar();
}
--------------

When I try to compile foo.c like this...
gcc -shared -o foo.dll foo.c

I get an error message complaning that '_bar' is undefined.


Thanks,
--Vikram
