Better things to do than support 8+ year old hardware. Most of these fixes seem to be added in case-by-case by the individual portfile maintainers.

I'm very much in favor of maintaining compatibility with older systems. The MacPorts project doesn't especially want to be in the business of forever maintaining patches to projects, if it can at all be helped. If upstream development has ceased we don't really have much choice but to use our own patches to fix problems, but if the developers still exist, then such matters should be reported to them for fixing, and if you can provide them with a fix that's suitable to be committed to their sources, so much the better.

But if you already have working portfiles adding local patches conditionally, that's wonderful, and we can certainly start with that; by all means file MacPorts tickets with your patches. And if upstream does not accept patches to maintain compatibility with older systems, then we can maintain those patches as long as it's practical.
