This was done by regex substitution with `sed`. I then manually went over the entire diff and fixed any incorrect changes. This diff also changes a lot of `callconv(.C)` to `callconv(.c)`, since my regex happened to also trigger here. I opted to leave these changes in, since they *are* a correct migration, even if they're not the one I was trying to do!
