BUG: Extending timeout of test 6 from 0.1 seconds to 3 seconds.  This should avoid missed signals and intermittent failures.

BUG: Drastically extending test5's timeouts to get it to pass when running on a heavily-loaded machine.

COMP: Added KWSys try-compiles KWSYS_STL_HAS_ALLOCATOR_TEMPLATE and KWSYS_STL_HAS_ALLOCATOR_OBJECTS.  Needed for more old-stl support in the hashtable.

BUG: When killing a child all the pipe read ends should be closed.  This will allow a child that is blocking while waiting to write to the pipe to wake up and receive the kill signal properly on cygwin.

BUG: Expanded difference in timeouts between tests 4 and 5 so that 5 does not timeout while waiting for 4 to timeout.  This should fix the intermittent failure of test 5 on cygwin.  ENH: When a mismatch is reported it now reports what it was as well as what it should have been.

BUG: For some reason the non-template allocator test compiles on VS6 even though its allocator is a template.  Adding ::size_type to be sure it accesses a member of the allocator.

BUG: Cannot use Win32 implementation for cygwin processes because then cygwin paths to executables like /usr/bin/ls are not found.

COMP: Added KWSYS_CXX_HAS_CSTDDEF try-compile to KWSys to provide kwsys/cstddef header (to get size_t for hash_fun.hxx).

ENH: Changing kwsysProcess implementation on Cygwin to use the Win32 implementation instead of the UNIX implementation.  This makes dealing with misbehaving children work better.  The KWSys Win32 process implementaion is more robust than the Cygwin implementation (partly because it doesn't have to exactly reproduce the POSIX api).

ENH: Added KWSys try-compiles KWSYS_STL_HAS_ITERATOR_TRAITS, KWSYS_STL_HAS_ITERATOR_CATEGORY, KWSYS_STL_HAS___ITERATOR_CATEGORY, and KWSYS_STL_HAS_ALLOCATOR_NONTEMPLATE to get the hash table to compile on old HP and Sun compilers.

COMP: Replacing _Select1st with a specialized hash_select1st that avoids requiring the stl pair to have first_type defined.  The old HP STL does not define first_type and second_type in its pair.

ENH: Added KWSYS_CXX_HAS_ARGUMENT_DEPENDENT_LOOKUP try-compile to KWSys.  Needed to optionally bring hash table comparison operators into the global namespace when argument dependent lookup is not supported.

COMP: Remove friend templates and always use template friends (possibly with <>).  Needed to work-around Sun CC bug.

COMP: Removing return value from test6.  It is an infinite loop, so the return causes warnings.  It will never return anyway.

COMP: Adding work-around for CMake dependency scanning limitation.  Any configured header included by KWSYS_HEADER() in a .c or .cxx file in kwsys itself must use this hack to get dependencies.
