I actually don't see it for a small number, ie: * xtensa-linux * fr30-elf * hppa2.0-hpux11.9 * hppa64-hpux * hppa64-hpux11.0 * hppa64-hpux11.3 * ia64-elf * ia64-hpux * mmix-knuth-mmixware * powerpc-darwin7 * pdp11-aout * powerpc-darwin8 * s390x-ibm-tpf * x86_64-apple-darwin Maybe you had a lucky pick? Only IPv6 connectivity at the moment, but here are a few (failed) build logs for more common targets: http://wolf.lug-owl.de:8080/jobs/gdb-alpha-netbsd/6 http://wolf.lug-owl.de:8080/jobs/gdb-m68k-linux/6 http://wolf.lug-owl.de:8080/jobs/gdb-mips-linux/6 http://wolf.lug-owl.de:8080/jobs/gdb-powerpc-linux/6 http://wolf.lug-owl.de:8080/jobs/gdb-x86_64-linux/6 MfG, JBG --=20 --ndwjmp47cxr2o2dz Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iF0EABECAB0WIQQlDTvPcScNjKREqWEdvV51g5nhuwUCYTWvFAAKCRAdvV51g5nh u1OCAKCOaezmPwW0fwKvxf/qjzFDEgTRZQCfRsiSEtMjhIKGh9LZ5cMtCvTgbrc= =gkLT -----END PGP SIGNATURE----- --ndwjmp47cxr2o2dz--
