This patch adds the MT allocator graciously donated by Stefan Olsson and Ola Rönnerup. It also re-organizes the allocator code to improve legibility and to make it more modular. I think this is the right way to go, and would like to check this in. However, I'll wait for 24 hrs for comments. As people may be aware, the 3.4 branch creation deadline is looming, so CVS intensive work should be done by the end of the week. Things that may be done after this patch is in: 1) splitting __gnu_cxx into public/private or adding nested namespaces for this. Please discuss this on a separate thread. 2) removing some of the allocator_traits.h bits. 3) trying to figure out a better way to switch default allocators, ie extensions to _GLIBCPP_FORCE_NEW. tested x86/linux -benjamin 2003-06-10 Benjamin Kosnik <bkoz@redhat.com> * include/bits/stl_alloc.h (__debug_alloc): Move out.
