Um, you can't detect it at compile time except that, if ICU is not in the
users include path then boost/regex/icu.hpp won't compile. You will also
get linker errors if you attempt to use ICU support and the library was
built without it. So.... an AC_TRY_LINK in your configure script along with
a minimal test program that invokes a u32regex would do the trick.
