Thanks; I updated the pkgsrc entry to require C99 (not that anyone uses pkgsrc with pre-C99 compilers). > Most issues encountered are with newer verions of compilers due to > introducing new warnings/optimizations and are not related to the > underlying OS.

That's fair enough if there are some other older systems in CI. Certainly doesn't need to be Ubuntu. I didn't realize there was coverage for oldest-sane-gcc.
