Don't cast through "volatile int". Causes a gcc warning nowadays. XXX: should put something else back here to frighten the optimizer

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	4 It is old and not very well designed. It is still here, and sort of
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	5 being maintained, because (1) some of the examples use it, and (2)
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	6 somebody out there might even be using it.
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	7
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	8 It should be considered deprecated. The examples will be migrated away
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	9 from it over time; anyone using it in their own code should move to
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	10 something else - whether AnaGram's own AGCLIB1 or the STL or whatever.

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	14 Changes to oldclasslib since the AG 2.01 release:
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	15
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	16 - Updated the syntax for friend template functions for the current (or
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	17 at least recent) dialect of 'standard' C++.
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	18
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	19 - Added const qualifications in various places to allow use of string
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	20 constants. In current C++ string constants have type "const char *";
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	21 that was not the case when this code was written.
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	22
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	23 - Added explicit calls to base class constructors even when they take
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	24 no arguments; gcc 3.3 whines if you don't have these.
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	25
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	26 - Removed the behavior where you can cast a stack<> to T* or a
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	27 character_sink to char* to fetch the topmost element. Now you must
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	28 call the top() method instead. Apparently the C++ standard says that
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	29 having such a cast operator and also having operator[] is ambiguous,
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	30 because you can convert the object to a pointer and apply [] to that
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	31 as well as using the provided operator[] directly. This seems stupid
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	32 bordering on insane, but when compilers start citing the standard at
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	33 you there isn't much choice but to go along.
6 607e3be6bad8 Adjust to the moving target called the C++ standard. David A. Holland parents: 0 diff changeset	34
607e3be6bad8 Adjust to the moving target called the C++ standard. David A. Holland parents: 0 diff changeset	35 - Added explicit assignment operator definitions in places where gcc
607e3be6bad8 Adjust to the moving target called the C++ standard. David A. Holland parents: 0 diff changeset	36 10.x now refuses to produce them automatically. Added missing "const"
607e3be6bad8 Adjust to the moving target called the C++ standard. David A. Holland parents: 0 diff changeset	37 to some of the copy constructor arguments.
