This would make it impossible to build libstdc++ with clang, and why = remove MK_GNUCXX at all[1]? Maybe the option should be renamed to = MK_LIBSTDCXX or MK_LIBSTDCPLUSPLUS, since that is basically what it = does: enable or disable building libstdc++ and its dependent components. If the compiler is base gcc, you *must* build libstdc++, since it cannot = build libc++. But if you are using e.g. gcc 4.8 as an external = toolchain, you could just as easily disable libstdc++, and build libc++ = instead. I think both should be a user-selectable option. -Dimitry [1]: That is, unless somebody is planning on removing libstdc++ = altogether... but then g++ will also have to go. ;) --Apple-Mail=_98D5528D-DD30-44B5-8F37-9BEC487F512A Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) iEYEARECAAYFAlO7lhAACgkQsF6jCi4glqPEXACgw/jzs5IZTiZ6qa4Ikc8ozTEN lkwAoMWS5UJShWpYmoICfewrfBfF4Xkl =qqwi -----END PGP SIGNATURE----- --Apple-Mail=_98D5528D-DD30-44B5-8F37-9BEC487F512A--
