On Linux, I see only one symbol here. In addition, natLogger.o
has a weakly-defined getName() ("W" in nm's notation).

Since natLogger.cc doesn't explicitly define getName(), I guess
this is the result of a funky interaction between using
#pragma interface/implementation and weak symbols support:

  http://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Interface.html

But 4.0 should have weak symbols support for Cygwin/MinGW:

  http://gcc.gnu.org/ml/gcc-cvs/2004-11/msg00265.html

So I am confused...

Maybe you can create a simple C++ testcase demonstrating
this problem on MinGW and submit a PR. If possible, also
test that testcase with GCC 3.4.x and see if it is a
regression on Win32.
