  Fix for Issue #1370; allow exit values not in exitvalmap.  Added some tests for this kind of thing.  Also improved win32 err msg if command exits with nonzero to show actual cmd, not just "cmd.exe".  Note this fix improves posix and win32 behavior.

  Move all the scons.org stuff from the scons source tree itself to a
  directory next to the trunk, and delete the copies from the branches.
  There's a lot of stuff there (what with all of the documentation of
  the different versions) and it's ridiculous to make everyone sync it
  just to work on the code.

+#!/usr/bin/env python
+#
+# Quick script to process the *summary* output from SCons.Debug.caller()
+# and print indented calling trees with call counts.
+#
+# The way to use this is to add something like the following to a function
+# for which you want information about who calls it and how many times:
+#
+#       from SCons.Debug import caller
+#       caller(0, 1, 2, 3, 4, 5)
+#
+# Each integer represents how many stack frames back SCons will go
+# and capture the calling information, so in the above example it will
+# capture the calls six levels up the stack in a central dictionary.
+#
+# At the end of any run where SCons.Debug.caller() is used, SCons will
+# print a summary of the calls and counts that looks like the following:
+#
+#       Callers of Node/__init__.py:629(calc_signature):
+#                1 Node/__init__.py:683(calc_signature)
+#       Callers of Node/__init__.py:676(gen_binfo):
+#                6 Node/FS.py:2035(current)
+#                1 Node/__init__.py:722(get_bsig)
+#
+# If you cut-and-paste that summary output and feed it to this script
+# on standard input, it will figure out how these entries hook up and
+# print a calling tree for each one looking something like:
+#
+#   Node/__init__.py:676(gen_binfo)
+#     Node/FS.py:2035(current)                                           6
+#       Taskmaster.py:253(make_ready_current)                           18
+#         Script/Main.py:201(make_ready)                                18
+#
+# Note that you should *not* look at the call-count numbers in the right
+# hand column as the actual number of times each line *was called by*
+# the function on the next line.  Rather, it's the *total* number
+# of times each function was found in the call chain for any of the
+# calls to SCons.Debug.caller().  If you're looking at more than one
+# function at the same time, for example, their counts will intermix.
+# So use this to get a *general* idea of who's calling what, not for
+# fine-grained performance tuning.
