remove unused state variable
remove deprecated register declaration, trust the compiler
don't expose 'unsigned long long' to C (C99)
use triple-underscore to avoid reserved keyword
don't use register storage specifier anymore
C++ standard library portability improvements (tested against libc++)
no more direct use of std::_Select1st
move a few echo- make targets up to global level
fix default allocator template argument for unordered_map
instantiates template in home namespace
when checking C++ library for reverse_iterator comparisons and copy_if algo,
use the namespace determined by the versioned namespace check (libc++)
proper test for reverse_iterator comparison and copy_if
previous test failed for wrong reason -- header not found
now test points to $srcdir/util/STL/libconfig.hh
fix tests and uses of non-std _Identity, _Select1st, _Select2nd
proper test whether C++ library provides begin(valarray) and end(valarray)
need <iostream>
static_cast to base sequence type where access to private push_back needed
lexer: strip away deprecated 'register' storage class specifier
fix uses of ::what ostream& return value
cannot assume that a vector::const_iterator has public constructor
fix by using random_access_iterator arithmentic into an array
remove unneeded forward declarations
