Problems using log4cxx built on Solaris 8!

Hello everybody,
 I have compiled the log4cxx and built the shared library on Solaris 8 platform.
While I link this library dynamically to build my executable, I see the following error:
---------------------------------------------------------------------
Undefined                       first referenced
 symbol                             in file
long __rwstd::InterlockedDecrement(long*)        /home/hatinm/projects/c++_logging/log4cxx-0.9.7/lib/liblogcxx.so
long __rwstd::InterlockedIncrement(long*)          /home/hatinm/projects/c++_logging/log4cxx-0.9.7/lib/liblogcxx.so
long __rwstd::InterlockedExchange(long*,long)   /home/hatinm/projects/c++_logging/log4cxx-0.9.7/lib/liblogcxx.so
ld: fatal: Symbol referencing errors. No output written

The following is the output of nm -o -C liblogcxx.so | grep Interlocked

1) How is the scope for the undefined symbols being resolved to __rwstd:: ??
2) Another thing I notice is that these functions (Interlocked*) occur only in 3 source files: condition.cpp, thread.cpp, objectimpl.cpp.

    The references in the last file objectimpl.cpp are to the functions Thread::Interlocked*. Hence, these are being resolved.

    In the other 2 files, condition.cpp thread.cpp, whatever references exist (barring the definition of the member version of Thread class), they should've

    been EXCLUDED out by the pre-processor (controlled by pre-processor macros like HAVE_MS_THREAD) !!! I have duly defined the macro

    HAVE_PTHREAD.

I would greatly appreciate your suggestions/ ideas on how to resolve this.

Hatinder
