 On the Solaris following test case cannot be compiled by Sun C++.

 {{{
 % cat test.cc
 #include <boost/asio.hpp>
 int main()
 {
     return 0;
 };
 }}}
 {{{
 % CC -V -c -library=stlport4 -I$BOOST test.cc
 CC: Sun C++ 5.9 SunOS_sparc Patch 124863-06 2008/07/08
 $BOOST/boost/asio/detail/socket_ops.hpp", line 218: Error: Cannot assign
 void* to char*.
 $BOOST/boost/asio/detail/socket_ops.hpp", line 229: Error: Cannot assign

 $BOOST/boost/asio/detail/descriptor_ops.hpp", line 72: Error: Cannot

 }}}
 The problem exists in the 1.35, 1.36 and trunk.

 On the Solaris while code compiled by Sun C++ iovec::iov_base field has
 type caddr_t, which is a typedef, usually for char*. So it is impossible
 to assign void* to it without explicit cast.

 Suggested patch is attached.
