	where all development documents are stored.

<language> One of the most used {object-oriented} languages, a
	superset of {C} developed primarily by {Bjarne Stroustrup}
	<bs@alice.att.com> at {AT&T} {Bell Laboratories} in 1986.

	In C++ a {class} is a user-defined {type}, syntactically a
	{struct} with {member functions}.  {Constructors} and
	{destructors} are member functions called to create or destroy
	{instances}.  A {friend} is a nonmember function that is
	allowed to access the private portion of a class.  C++ allows
	{implicit type conversion}, {function inlining}, {overloading}
	of operators and function names, and {default function
	arguments}.  It has {streams} for I/O and {references}.

	C++ 2.0 (May 1989) introduced {multiple inheritance},
	{type-safe linkage}, pointers to members, and {abstract
	classes}.

	C++ 2.1 was introduced in ["Annotated C++ Reference Manual",
	B. Stroustrup et al, A-W 1990].

1. <character> 0, {ASCI} character 48.  Numeric zero, as
	opposed to the letter "O" (the 15th letter of the English
	alphabet).  In their unmodified forms they look a lot alike,
	and various {kluges} invented to make them visually distinct
	have compounded the confusion.

	If your zero is centre-dotted and letter-O is not, or if
	letter-O looks almost rectangular but zero looks more like an
	American football stood on end (or the reverse), you're
	probably looking at a modern character display (though the
	dotted zero seems to have originated as an option on {IBM
	3270} controllers).  If your zero is slashed but letter-O is
	not, you're probably looking at an old-style {ASCII} graphic
	set descended from the default typewheel on the venerable
	{ASR-33} {Teletype} (Scandinavians, for whom slashed-O is a
	letter, curse this arrangement).

	If letter-O has a slash across it and the zero does not, your
	display is tuned for a very old convention used at {IBM} and a
	few other early mainframe makers (Scandinavians curse *this*
	arrangement even more, because it means two of their letters
	collide).  Some {Burroughs}/{Unisys} equipment displays a zero
	with a *reversed* slash.  And yet another convention common on
	early {line printers} left zero unornamented but added a tail
	or hook to the letter-O so that it resembled an inverted Q or
	cursive capital letter-O.

	2. To set to zero.  Usually said of small pieces of data, such
	as bits or words (especially in the construction "zero out").

	3. To erase; to discard all data from.  Said of disks and
	directories, where "zeroing" need not involve actually writing
	zeroes throughout the area being zeroed.  One may speak of
	something being "logically zeroed" rather than being
	"physically zeroed".

<software> A program by {Richard Stallman} to discover
	properties of the current {platform} and to set up {make} to
	compile and install {gcc}.

	{Cygnus configure} was a similar system developed by
	K. Richard Pixley in collaboration with Richard Stallman.
	In 1994, David MacKenzie and others modified {autoconf} to
	incorporate all the features of Cygnus configure and many
	{GNU} programs, including gcc now use autoconf.

	{Metaconfig} is a similar program used in building {Perl}.

A language proposed by Cii {Honeywell-Bull} to meet the DoD
	{Ironman} requirements which led to {Ada}.  This language won
	in 1979.
