Re: <iconv.h> creates incorrect iconv() prototype

[Paul Eggert]

The iconv build procedure prefers to use 'char **',
but it uses 'const char **' if it detects that it's
on a platform where the 'const' is needed.  Evidently
that part of the detection isn't working.  Can you
look at config.log and see what went wrong on your platform?
Look for the string "for iconv declaration".  Thanks.
