Tweak PDL::howbig pod so apropos sizeof will find it
make t/gd_oo_tests.t TODO to debug

There is a bug for AMD64 platforms that has not
been resolved.  The sf.net bug #3518190 is being
re-opened to track the issue.
Add -glut option to perldl pod (now works for non-MSwin platforms)
Update Known_problems and Release_Notes for CPAN release
Update VERSION to 2.4.11_004 for more development
Make perldl skip and warn that -glut/-tk options not supported

Yet...until I can figure out how to get the event loops
to interoperate correctly.
Merge branch 'master', remote-tracking branch 'sf/master'
New FullDoc PDL::PP key and fixed a few minor doc niggles
