// 16 Feb 2001 Added a missing const. Made the tests run (somewhat) with

// plain MSVC again. (David Abrahams)
|

// 11 Feb 2001 #if 0'd out use of counting_iterator on non-numeric types in
|

// MSVC without STLport, so that the other tests may proceed
|

// (David Abrahams)
|

// 04 Feb 2001 Added use of iterator_tests.hpp (David Abrahams)
|

// 28 Jan 2001 Removed not_an_iterator detritus (David Abrahams)

// Revision History
|

// 30 Nov 01 Added permutation_iterator.(Toon Knapen)
|
||||
// 19 Nov 01 Added generator_iterator. (Jens Maurer)
|
||||
// 04 Nov 01 Updated with respect to change in named parameters.
|
||||
// (Jeremy Siek)
|
||||
// 08 Mar 01 Moved indirect and transform tests to separate files.
|
||||
// (Jeremy Siek)
|
||||
// 19 Feb 01 Take adavantage of improved iterator_traits to do more tests
|
||||
// on MSVC. Hack around an MSVC-with-STLport internal compiler
|
||||
// error. (David Abrahams)
|
||||
// 11 Feb 01 Added test of operator-> for forward and input iterators.
|
||||
// (Jeremy Siek)
|
||||
// 11 Feb 01 Borland fixes (David Abrahams)
|
||||
// 10 Feb 01 Use new adaptors interface. (David Abrahams)
|
||||
// 10 Feb 01 Use new filter_ interface. (David Abrahams)
|
||||
// 09 Feb 01 Use new reverse_ and indirect_ interfaces. Replace
|
||||
// BOOST_NO_STD_ITERATOR_TRAITS with
|
||||
// BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION to prove we've
|
||||
// normalized to core compiler capabilities (David Abrahams)
|
||||
// 08 Feb 01 Use Jeremy's new make_reverse_iterator form; add more
|
||||
// comprehensive testing. Force-decay array function arguments to
|
||||
// pointers.
|
||||
// 07 Feb 01 Added tests for the make_xxx_iterator() helper functions.
|
||||
// (Jeremy Siek)
|
||||
// 07 Feb 01 Replaced use of xxx_pair_generator with xxx_generator where
|
||||
// possible (which was all but the projection iterator).
|
||||
// (Jeremy Siek)
|
||||
// 06 Feb 01 Removed now-defaulted template arguments where possible
|
||||
// Updated names to correspond to new generator naming convention.
|
||||
// Added a trivial test for make_transform_iterator().
|
||||
// Gave traits for const iterators a mutable value_type, per std.
|
||||
// Resurrected my original tests for indirect iterators.
|
||||
// (David Abrahams)
|
||||
// 04 Feb 01 Fix for compilers without standard iterator_traits
|
||||
// (David Abrahams)
|

// 13 Jun 00 Added const version of the iterator tests (Jeremy Siek)
