How those options are supposed to be specified? Only by user, in any
combination he might want? Also, by "on XXX and YYY" -- I suppose you
mean target-os, not host-os?

Did you mean "off" as the last word?

Would you please either specify code that compiles and links with
iconv and does not compile or does not link without? Alternatively,
point me at existing checks? CMake does not appear to have such
check in 2.6.

I'm fairly sure you can do this last one yourself easily, no?

Why? That would make Boost.Locale different from every other compiled
library.

You have not said anything about either posix, or std, or winapi backend, 
or how they are enabled.

Why does this depend on Boost version?

I can look into this, but before -- can you give me a link to "golden" sources
of Boost.Locale, or better still -- to live version control system where it
lives. Write access would be slightly better.
