Description
parNewGeneration.cpp contains a WIN32 conditionalized #pragma to disable C4786: identifier was truncated to '255' characters in the debug information.  This warning appears to be specific to old versions of MSVC++ (version 6.0 and earlier); see http://support.microsoft.com/kb/195386

MSVC++ 6.0 is long dead.  The #pragma to disable the warning can be removed.
