Attached is the output of "gcc -ansi -dM". I hope it contains enough information to answer your questions. Note also that _REENTRANT is not defined here, therefore its source must be somewhere outside of gcc.
John, I attached a diffent patch for the file to this mail which fixes the problem. First of all, the platform in question is Tru64 (not HP-UX). Next, when the file is included by the compiler, _GLIBCPP_HAVE_GTHR_DEFAULT is _not_ defined. Therefore I changed the check to __osf__ && !_REENTRANT to just unconditionally define _REENTRANT on Tru64. If the patch is ok for you, please go ahead and commit it or just tell me and I will commit it myself.
