For example?

Will it cover all the clauses from standard specification? How long will it

Actually I would be more interested in old sun and gcc compilers. But this
is beyond the point.

No. I think it would be a waste to invest your efforts to try to make it
compile for old compilers. After all those users who interested in compiling
custom preprocessor should be able to get a hold of latest gcc.

Oh! I know numerous example like that. I had an unfortunate need to modify
some behavior in doxygen recently - and I really disliked the way it's
written. But it doesn't make this tool less valuable. Note I am not saying
anything about the wave library - I did not (and should not) look into it's

I believe we (boost) need a formal notion of a tool that is delivered as a
binary plus source code for those platforms we did not provide binary for.
BTW binary shouldn't be a part of main delivery packager - only docs should.

Let's say I want an apple sauce. Instead you giving me an apples (they may
be good ones or not so much, since for sauce it doesn't really matter and
why waste good apples on sauce) and saying that if I have powerful enough
mixer (or whatever it called) I could get a sauce in just a second. And the
reason you are telling me is that there are some people out there who may've
want slightly less sugar. I believe it's not good enough: give me my sauce -
I do not want spend time making one, I do not have an appropriate mixer and
I do not have a space to store all these apples.
