Uh, where did you get that idea?  Please cite chapter and verse.  Some
earlier drafts of ANSI C restricted pointer conversions so that this sort
of conversion was not strictly conforming; the result was loud protests
and the problem was fixed.

It is true that you have to beware of alignment in such conversions, but
that is not an issue here.  It is also true that if you use such a converted
pointer to attempt to modify a "const char" variable, all bets are off.  But
the conversion itself is strictly conforming.
