Current sources don't compile on AIX with xlc compiler because of the
combined (and inconsistent ? or compiler bug) use of extern and static
for the datetktbl in datetime.c.
header unconditionally has:
extern datetkn datetktbl[];
source has:
static datetkn datetktbl[] = {
The usual approach would be to avoid that line in the header if included
from datetime.c, but I think it would be better to use a const in this
case.
I think this is a general compatibility problem, and thus needs to be
solved.
