Turns out to be tricky to make this warning into an error because it's
enabled by default, and not with an explicit -W switch. The only way to
get it treated as an error is to turn on -pedantic-errors, but that also
turns on -pedantic, which we don't want as that complains about all of
the GCC extensions that we use. So, you turn that back off with
-Wno-pedantic:

        CFLAGS = -pedantic-errors -Wno-pedantic

We're definitely not ready for this though; it also turns casts from
'const char *' to 'char *' into errors. Getting one 'this can never
work' bug converted into a raft of 'this essentially always works'
spurious error messages just isn't helpful.

I think so; the alternative is to break hardware cursors on any driver
which hasn't been updated. Anyone else have a second opinion?
