  Log:
  Depending on how a compiler generates code (e.g., GCC 3.2.2 vs. GCC
  3.0.1), a bug in the gcc3_linux_intel UNO bridge is revealed:  If a
  C/C++ function returns a complex object (class, struct, union), the 386
  ABI specifies that the caller pushes the address for that object on the
  stack, and the callee removes it from the stack.  The code in the UNO
  bridge (callVirtualMethod in
  bridges/source/cpp_uno/gcc3_linux_intel/uno2cpp.cxx) erroneously assumes
  that the callee does *not* remove the address from the stack, corrupting
  the stack.
  
  We use the same bridge code as linux does for gcc3.x. So this fix also
  works for us.
