Thank you for your reply, erik.

But I don't quite follow you. Are you suggesting that the error has nothing to do with "opnames" and "etnames", but is about the following word "memccpy"?

I had grep opnames and etnames before, and finds only one initial place.
And I grep memccpy, no result was found.
There is a strange situation, when I "8l subr.c" then it's "memccpy", when I
"8l *.8", it shows "create":

(2050) DATA ...(same as before)
create: multiple initialization.
...(same as before)
create: multiple initialization.

I suspect it is opnames and etnames that cause the problem, and I find something
strange in the subr.c and it's included file go.h, is it relevant?
