[Libreoffice] Changing patches

Hi!

One of the issues I see is in SampleICC, where Vetters.cpp includes
<errno.h> on Solaris and <sys/errno.h> on all other non-Windows.

On NetBSD, it also needs to include errno.h to compile. I could add an
#if NetBSD to the Solaris case, but I don't think that sys/errno.h is
standardized and thus prefer to make it include <errno.h> on all
non-Windows platforms instead. What do you think?

The next question is how to change this, since the sys/errno.h include
gets added by one of the patches coming with LO. You probably already
have a tried-and-true workflow for this, what is it? :)

Thanks,
 Thomas
