[Bug c++/14962] g++ appears to ignore #pragma redirect_extname

As an extra bonus, gcc-3.2.3 on solaris (same machine) appears to be fubared
when it comes to largefile support as well. Even if you don't define anything on
the command line, gcc -v reveals that it defines both -D_LARGEFILE_SOURCE=1 and
-D_LARGEFILE64_SOURCE=1 which completely breaks largefile support if you just
want _LARGEFILE_SOURCE and not _LARGEFILE64_SOURCE, you can't have it.
gcc-3.3.3 at least avoids this issue. (This is why it's a bit pointless to test
with gcc-3.2 -- the extra define drops the #pragmas from the output anyway)
