I had a few in-progress changes from a week or two ago, and am clearing the decks.
I added a new build-checking rule (coming separately) and it exposed an unnecessary include:

So we have a way to find header files which are unused?
No - this is impossible unless you have a copy of every OS we've ever tested on. It may be unused on Linux, but may be needed on Solaris, etc etc. Removing <getopt.h> is an obviously safe action, but in general we should be wary of removing supposedly unused heads.
Surely we can do it for POSIX calls?
Of course the OS / libc itself may not obey POSIX ...
Yeah, I'm not convinced any OS is fully compliant with POSIX header file definitions - particularly when you get into more obscure platforms like win32/cygwin, or even just slightly older Linux. And we're compiling with the _USE_GNU extension defined so the headers we're including on Linux aren't even in POSIX compliant mode anyway Dan. -- |: Red Hat, Engineering, Boston -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
