Please add ICU as dependency to Boost (i.e. change the "--without-icu" to "--with-icu") - thoughts?

[Tinker]

Hi,

I need the ICU parts of Boost. And, I really guess internationalized 
stuff is becoming more and more popular.

Currently:

     /usr/ports/devel/boost$ grep -r icu *
     Makefile:               --without-icu \

Would you feel like changint that to --with-icu, and then adding "icu4c" 
as a dependency to boost as to provide for that?

Thanks!
Tinker
