[Mono-list] Globalization: ICU, unsupported. Version: 3.2 question

[Aleksandar Dezelin]

What does exactly mean 'unsupported' reported by the configure script:

 mcs source:  $(top_srcdir)/mcs
        GC:          boehm
        Globalization:     ICU, unsupported. Version: 3.2
        TLS:         __thread
        SIGALTSTACK: no
        Engine:      Building and using the JIT
        2.0 Alpha:   no
        JNI support: IKVM Native

Another simple question: 

There are two options for parameter '--with-gc='  : boehm and included.
Which one is better?

Cheers,
Aleksandar Dezelin
