Build errors under Solaris 11

[EwanColdicott]

When building under Solaris 11 with gcc 4.6.3 (downloaded from OpenCSW), any use of the standard library class map generates error messages. For example:
./sources/LUAClient.cpp:56:4: error: reference to map is ambiguous
/usr/include/net/if.h:97:9: error: candidates are: struct map
/opt/csw/lib/gcc/i386-pc-solaris2.10/4.6.3/../../../../include/c++/4.6.3/bits/stl_map.h:88:11: error: template<class _Key, class _Tp, class _Compare, class _Alloc> class std::map

i.e. there's a conflict between the system type struct map and C++ library class map.
Solution is to specify std::map in order to remove the ambiguity. Will submit pull request separately.
