Does the linker command show that it's being linked to ICU?
Come to that if the compiler command line has BOOST_HAS_ICU set, then you
*will* get compiler errors if it's not being built against ICU.
Stupid question, but are you sure that you're looking at the correct
binaries?

-sHAVE_ICU has no effect in 1.44 - it should detect and configure it
automatically.
When you build there should be a message something like:
Performing configuration checks
- has_icu builds : no
And if you see a "no" here then look in bin.v2/config.log to see the actual
error messages that caused the configure check to fail.
HTH, John.
