Graph with MPI fails to compile due to mismatch between size of types

[webmaster@…]

[BOOST_PATH]/boost/graph/distributed/unsafe_serialize.hpp(40) : error C2182: 'abstract declarator' : illegal use of type 'void'

This error occurs during x64 compilation with MSVC 10.0 under Windows 7 x64, where sizeof(int) != sizeof(void*) && sizeof(long) != sizeof(void*).

typedef mpl::if_c<(sizeof(int) == sizeof(void*)),

int, mpl::if_c<(sizeof(long) == sizeof(void*)), long, void>::type

::type ptr_serialize_type;

As Windows uses LLP64 model, which defines a long type as 32bit integer, two cascaded conditions fail. Then ptr_serialize_type is declared as a void type. I think it can be fixed with replacing the last 'void' with 'long long' or using conditional compilation for windows under x64.

Could you please check this in the Boost trunk? It appears to have been fixed there.

I found the problem has been fixed in version 1.44. It was in version 1.43. Thanks.
