6851,64bit build error on Solaris with gcc 4.4.5 and ICU,alasdairrr@…,Artyom Beilis,"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:
