From 308aed9b3951f347d123125fdf7e6bd0f313feb3 Mon Sep 17 00:00:00 2001
From: Joel Sherrill <joel.sherrill@OARcorp.com>
Date: Mon, 27 Apr 1998 13:49:42 +0000
Subject: Added numerous entries to make the memory calculation more accurate:

  + POSIX threads
  + Ada tasks
  + POSIX threads API support
  + POSIX condition variables
  + POSIX keys (still do not account for data fields)
  + POSIX mutexes
  + POSIX queued signals
  + added macro for extra memory for task stacks
  + default value for CONFIGURE_MAXIMUM_FAKE_ADA_TASKS
  + extra memory for Ada task stacks
