I reproduced the issue on the autobuilder machine. The message is the
following one:

gcc.compile.c++ bin.v2/libs/locale/build/gcc-4.7.3/release/boost.locale.posix-off/threading-multi/icu/formatter.o

It looks similar to https://svn.boost.org/trac/boost/ticket/6851 but
this link doesn't give much clue about the solution, except one patch
that was apparently not official integrated. Some other people had it
more recently,
http://comments.gmane.org/gmane.comp.lib.cppcms.user/2125.

I'm not really familiar enough with how typing works in C++ to cook a
patch for this. Anyone?

Thanks,

Thomas
