This is a wrong fix. The 'configure' script should detect the iconv library:

check_cc_snippet libiconv '
#include <iconv.h>
int test(void)
{
  iconv_t ic = iconv_open("ASCII", "ASCII");
  return 0;
}
' -liconv

Could you check why check_cc_snippet does not fail in your system?

This is a right configure output for libc based systems:

  checking for cc libiconv ...                      fail

So even though the libiconv test fails (mine is a glibc system), iconv is used ( or something else for format conversions)?
Sorry to be nitpicking, I just want to package it right...

yes, iconv is mandatory for tvh.. see src/intlconv.c

What is idea of function duplication of libraries?

Better to change result message in configure.

The configuration output is correct libiconv means external iconv library, the build-in iconv in libc is a different thing.
