  You can *reasonably* expect the documented behaviour from the compiler.  Or
you can *un*reasonably ignore the documentation, make ill-informed guesses
about what the compiler ought to do, and complain when they turn out not to be
correct.

  No, you are merely ignorant of the facts.  As it clearly says on the changes
page:

(notice no mention of constexpr there) and if you follow the link to the C++0x
implementation status page:

http://gcc.gnu.org/gcc-4.5/cxx0x_status.html
> Language Feature  			Proposal  	Available in GCC 4.5?

so any disappointment is caused solely by your own baseless assumptions and
failure to properly read and comprehend what was in front of your eyes.

  Please, don't trouble yourself with adding insincere thanks to an insult;
it's not worth the effort for you or anyone else so you may as well save
yourself the time.

    cheers,
