Yes, that's apparently right.  As I wrote, "I would love to...", because
time has gone a bit over that naming scheme and I think, changing the
names to reflect their usage in a more general way would help when reading
the code in future.

Is it ok to rename them?

I used sources sources (erm...) to evaluate these results, exactly
CVS HEAD from 2004-09-08.  GCC was a 3.4 with SH2a patches applied.
