When we released Subversion 1.0 in 2004, we were still thinking we had better not use C'90 because it was only 14 years old and, you know, people need to be able to compile svn on systems of a reasonable age.
So we had a "strict C'89" policy. No "//" comments, for example. Now C'99 is 18 years old and C'90 is, ahem, 27 years old. Does anybody else feel like we're trapped in the dark ages? The only reason not to upgrade is our personal fear of "rocking the boat", it seems to me. Let's just do it? I know there is a problem with Microsoft not supporting C'99. C'90 should be fine though, and some of C'99 if we want to. WDYT? - Julian
