Well, we should at least document the flaw and the possible
workaround.  I wouldn't make the workaround the general solution,
however, not only due to the size, but AFAIR there were also issues
that the argument domain of asin/atan2 is different.

We should certainly rather see to fix asin, but please let me first
finish printf & Co.  I wouldn't even defer a possible release 1.0
for the asin/acos issue.
