 The following trivial patch fixes compilation of
 `boost/format/alt_sstream_impl.hpp` with Sun CC:

                  if(0 < prev_size)
 }}}

 I don't know why (as I don't know this code at all...) but `allocate()`
 returns `void *` and not `char *` in this STL implementation so it fails
 to compile without an explicit cast.

 Maybe there is a better way to deal with this but I hope that if no other
 solution is found, this patch could be applied to allow to use Boost with
 Sun CC with its (old and broken...) standard library.

 TIA!
