In gcc/auto-host.h I have #define HAVE_ICONV_H, whereas in libcpp/ I 
haven't.  From PR31932, I presume that HAVE_ICONV_H should never be 
defined.  The check is explicitly made in AC_CHECK_HEADERS in 
gcc/configure.ac.  I can't see what happens if I remove the check as 
fink symlinks autoconf-2.59 to autoconf which in turn is a symlink to 
autoconf-2.63.
