Please explain what these switches do (or point to documentation),
so we can find out whether it's the right thing for libtool to just
ignore and pass through these switches, or whether it would need to
take any further action.

Other than that, you can use `-Wc,FLAG' or `-Xcompiler FLAG' to get
flags by libtool, undetected, as a workaround.

Thanks,
Ralf
