v0.7

2005-04-16 Release 0.7
	* Removed vector inheritance from memblock.
		There are just too many problems with treating a vector
		this way. You can still do it explicitly by linking a
		memblock to the vector. Removing the inheritance causes
		vector to be non-virtual, which drastically reduces
		instantiation cost.
	* Removed elementSize, elementBytes member functions from cmemlink.
		Only vector inheritance needed elementSize.
	* Restricted vector link calls to T* instead of void*.
		This way there would be explicit casts to warn of weirdness.
	* Optimized vector push_back
	* ostream will now zero bytes skipped by align.
	* memblock will no longer zero newly allocated storage.
	* Inlined empty constructors on map,multimap,set,multiset.
	* NUMERIC_LIMITS macros to facilitate specialization.
	* Fixed string vformat problem crashing on x86_64
		Because vsnprintf is called twice, need to copy arglist.
	* Added an rm before ln in install to avoid "already exists" errors.
		SunOS still doesn't know about the -f flag...
	* Split the distribution into ustl and ustl-docs
	* New SIZE_OF_BOOL system substitution in bsconf
		Only Alpha and Mac have bool as a long, so a define is better.
	* Fixed configure being confused with multiple gcc versions.
	* Reduced Align code for nonstandard values.
	* Pulled up vector/tuple stream operators into generic container
		templates in uctrstm.h and made use of resulting macros.
	* New TEMPLATE_TYPE macros to allow template building with macros.
	* Fixed SSE3 detection in bsconf; thanks to Aloysius Indrayanto.
	* Fixed get_temporary_buffer to return size in elements, not in bytes.
		This is the proper behaviour as specified in the C++ standard.
	* Now using libc qsort in the sort algorithm.
		This may give you trouble if you are using a custom comparator
		that requires initialization outside the constructor. You can
		write a wrapper class that does the initialization in the
		constructor. Or, you can use stable_sort.
		I'm doing this to both speed up the common case and to reuse
		the functionality already linked to in libc. If you really
		need to have a sort with a parametrized comparator and don't
		want to change your code, file a bug report and I'll change
		it back. I just don't think anyone is using this type of
		construction.
