Problems cross-compiling bacula-5.0.1 for ReadyNAS Sparc

It looks as though the ready-made sparc cross-compiler package will not compile Bacula 5.0.1 - stat.h seems to have changed enough that the build fails like this:

Doh!

My latest attempt to cross-compile for sparc has meant setting up an Ubuntu 10,04 box, and I'm currently following this guide to get the cross-compile tools set up. It's not an area I know much about - although I "get" the theory behind cross-compiling, in the past, I've always just kept a build host for each architecture I'm building for (ultrasparc, alpha) and battled with drain-bamaged build environmnts as best I could. Hopefully, this initial pain of setting up a cross-compile environment will be worth it.

So far so good, then install libpq-dev (so I can --with-postgresql - you need to specify one DB to support when you compile, as there's no way to compile only the storage daemon).

Then ./configure --with-postgresql --host=sparc-linux-gnu and of course it bombs out here:

checking whether setpgrp takes no argument... configure: error: cannot check setpgrp when cross compiling

Agh, well how about not checking for it then?? I guess one day I'll have to learn how to use autoconf so I can fix this properly, but for now, edit configure to skip this check.
