 Hi,

 When doing a 64bit build of boost on Solaris with gcc 4.4.5, we're getting
 the following error:

 {{{

 }}}

 This is doing a 64bit build with ICU version v49.1.1 (although the same
 issue happens with 4.8.1.1).

 There are multiple definitions of of the formatter:format method, as can
 be seen here:

 http://svn.boost.org/svn/boost/trunk/libs/locale/src/icu/formatter.cpp


 This is the 32bit function definition with the call to icu_fmt:

 {{{
 virtual string_type format(int32_t value,size_t &code_points) const
 icu_fmt_->format(::int32_t(value),tmp);
 }}}

 However the 64bit one doesn't make a cast:

 {{{
 virtual string_type format(int64_t value,size_t &code_points) const
 icu_fmt_->format(value,tmp);
 }}}

 Fixing this with the following patch fixes the build:
