Assuming the standard Work directory that host the compiled files,
what  does
grep -3 ICONV_CHAR_PPTR_TYPE   source/Work/texk/xdvik/c-auto.h
say ?
ICONV_CHAR_PPTR_TYPE should be
const char **
but I think it's char **
and this case  we have to patch here
source/texk/xdvik/m4/xdvi-check-iconv.m4

# _XDVI_ICONV_CHAR_PPTR_TYPE
# --------------------------
# Check whether iconv takes a 'const char **' or a 'char **' input argument.
# According to IEEE 1003.1, `char **' is correct, but e.g. librecode
# uses `const char **'.
# Inspired by Autoconf's AC_FUNC_SELECT_ARGTYPES we do this without the need
# to run a test program or to use C++.
m4_define([_XDVI_ICONV_CHAR_PPTR_TYPE], [dnl
AC_CACHE_CHECK([for iconv input type],
               [xdvi_cv_iconv_char_pptr_type],
   [AC_COMPILE_IFELSE(
      [AC_LANG_PROGRAM(
         [[
/* iconv() definitions may differ depending on following macros ... */
#ifdef __hpux

#endif

#include <iconv.h>
         ]],
         [[extern size_t iconv(iconv_t, char **, size_t *, char**,
size_t*);]])],
      [xdvi_cv_iconv_char_pptr_type='char **'],
      [xdvi_cv_iconv_char_pptr_type='const char **'])])
AC_DEFINE_UNQUOTED([ICONV_CHAR_PPTR_TYPE], [$xdvi_cv_iconv_char_pptr_type],
                   [Define the type of the iconv input string (char ** or
const char **)])
]) # _XDVI_ICONV_CHAR_PPTR_TYPE

But the question is: why  are you having this problem now?
Iirc, on Sat 8 Feb your compilation was ok.
