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
apply previous lexer fix (remove 'register') to all *-lex-real.cc targets
include util/STL/functional.hh when we provide std::_Select2nd (template instantiated)
delete dead code
check whether <iterator> provides generic std::begin/end for containers
container_iterator.hh provides a fallback definition if missing
for libbogus (lexer/parser), squash the 'register' storage-specifier
