2018-11-16 10:40 AEST by Arthur Barrett - update gnu diff included in CVSNT in 'diff' folder?

The current version has problems compiling on GNUC 7 as explained in bug 7328 due to use of min() macro

2018-11-16 13:49 AEST by Arthur Barrett - The diff in cvsnt is from GNU DIFFUTILS 2.7:
http://ftp.gnu.org/gnu/diffutils/

This dates back to 1994(?) but has changes in ChangeLog that indicate it's been 'fixed' since, as part of the 
GNU CVS project.

At a minimum we should check for fixes to diff in CVS 1.x diff have been backported to CVSNT:
http://cvs.savannah.gnu.org/viewvc/cvs/ccvs/diff/diff.c?view=log

We should also do a 'diff' between our diff sources and the 'original' GNU DIFFUTILS 2.7 so we know what 
may need changing if we updated to something more recent...
