Portability patches vs 1.7.0.2 [3/6]

## Dangling commas in enum is not portable

Unfortunately there are a still a lot of vendor compilers that choke
when the last entry in an enum has a dangling comma (irix is one, and
I can get you a list of which of our particular platforms exhibit this
problem).

This patch simply deletes all the commas that are required to be able
to compile those enums on all of our supported architectures.

Cheers,
