That would indicate a problem (?) with the recent gpp*b.zip packages then.
From 4.7.4 on, they all come with libstdcxx.a in lib/.

If you think it should be kept, then I won't object too much.  A duplicate -L
entry indeed does no harm.  I'm just saying it's completely redundant - native
gcc will not work with an invalid DJDIR, and it will always put %DJDIR%/lib in
the default library path.
