Time goes by and patches get crufty. I'm attaching an updated patch; it 
has a bit more checking, but nothing drastic. All changes are 
extensions with the exception of the fix to the hashed associative 
container invalidation semantics, so if you've started looking at the 
second patch you haven't wasted your time. I can still commit the 
second patch and supply these bits separately.

Here is the list of changes for this version:

Version 3:
	* Checking for stream/streambuf iterators
	* Checking for heap algorithms
	* Checking for numeric algorithms
	* Checking for queue/priority_queue
	* Checking for stack
	* Checking for auto_ptr
	* Checking for basic_string (no safe iterators, but as many
	checks as we can do without ABI changes).
	* Checking for valarray
	* Fixed iterator invalidation rules for hashed containers
	* Added StrictWeakOrdering checks

Tested on i686-pc-linux-gnu and powerpc-apple-darwin; no new 
regressions when compiling in release mode, debug mode, or pedantic 
debug mode. Changelog and patch attached.
