[PATCH] codecvt.h

[David Edelsohn <dje at watson dot ibm dot com>]

	Both AIX and Glibc declare the second argument to iconv() as
"const char **".  The following patch removes the compiler error for me.
Have GNU/Linux systems seen the same errors?  I note a lot of ChangeLog
entries for codecvt.h enabling and disabling "const" for this same
function, so this needs some review.

Thanks, David


	* include/bits/codecvt.h (do_out, do_in): Constify __cfrom.
