Trying gcc-3.4.2 it has the same result as gcc-3.4.5 using master and 
Version2 branches.

Trying gcc-3.3.3 it complains:

"cc1plus.exe: error: unrecognized option `-Wextra'"

for every file whether using master or version2.

Whether type_traits should compile with these old gcc-3 versions is up 
to you.
