Remember, to determine if something is a type vs. an expression, autoconf performs TWO compilation tests, and relies on the fact that sizeof(expr) and sizeof((expr)) both compile, but sizeof(type) compiles while sizeof((type)) must fail. The back-to-back compilation is necessary to ensure that something being probed for is a type name rather than an arbitray expression. So just because _some_ tests fail (as expected) does not mean that this particular failure is where configure is messing up. --=20 Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org --UX5lskXjEANgoT76u7s0nNQxc8HjgkGn8-- --u2WvUKVSLRORIdgun9Ur2hwXrHp6xUSn5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" Content-length: 604 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJZOHvdAAoJEKeha0olJ0NqF5YH/Ar5rYnSRdMdJ8xZ6H5y9po/ BGO5wQvSdafpKzC8B7R3qCa7I3il4zdJA0n3FKVlnBbVeXEG9mF/34PFswlA/6AI xXK/RkOjkrLBMv2vu+wVTPt5g9uI2h+lY1bG/J4DGZ2RSAoT+uizRXdlPgItHfPm +rEWg23lRXlSrY9NQBauVpWAeKV/goQo0CTWOU5Gv/6e5PuwMYm0pBdINUwXY21j XzLWhUxjbf5PLXsLW+Np8jaIVVijW242NusH0+iXcRNgZbt+c+0HgnbWpm+jv0N1 mECPC7BsbPSAgMVCnV90rhXjRK/mGLldfCDq/9kiGBfMbZTJnCzWX7yQqHQ5mV8= =uUa7 -----END PGP SIGNATURE----- --u2WvUKVSLRORIdgun9Ur2hwXrHp6xUSn5--
