wvstreams ftbfs in ubuntu with gcc 4.5

When building wvstreams from source in ubuntu with gcc 4.5 the package fails to 
build due to gcc header not declared error 

Relavant part of the buildlog:

./CXX -c ipstreams/wvunixdgsocket
In file included from ./include/wvunixdgsocket.h:13,
                 from ipstreams/wvunixdgsocket.cc:1:
./include/wvaddr.h: In member function 'uint32_t WvIPAddr::addr() const':
./include/wvaddr.h:284: warning: dereferencing type-punned pointer will break 
strict-aliasing rules

attached it
