>Environment:
sparc-unknown-netbsdelf1.5 with the patch from
  http://gcc.gnu.org/ml/gcc-patches/2001-07/msg02242.html
>Description:
Some files include the following:

#ifdef HAVE_ICONV
#ifdef HAVE_LANGINFO_CODESET
  setlocale (LC_CTYPE, "");
  if (current_encoding == NULL)
    current_encoding = nl_langinfo (CODESET);
#endif /* HAVE_LANGINFO_CODESET */
#endif /* HAVE_ICONV */


The problem is that NetBSD/sparc-1.5 has a
/usr/include/langinfo.h that doesn't define CODESET.

>Fix:
gcc must check whether /usr/include/langinfo.h defines
CODESET.

libiconv-1.7 includes the following macro:

AC_DEFUN(jm_LANGINFO_CODESET,
[
  AC_CHECK_HEADERS(langinfo.h)
  AC_CHECK_FUNCS(nl_langinfo)

  AC_CACHE_CHECK([for nl_langinfo and CODESET], jm_cv_langinfo_codeset,
    [AC_TRY_LINK([#include <langinfo.h>],
      [char* cs = nl_langinfo(CODESET);],
      jm_cv_langinfo_codeset=yes,
      jm_cv_langinfo_codeset=no)
    ])
  if test $jm_cv_langinfo_codeset = yes; then
    AC_DEFINE(HAVE_LANGINFO_CODESET, 1,
      [Define if you have <langinfo.h> and nl_langinfo(CODESET).])
  fi
])
