[PATCH] test for libiconv in configure

[Benjamin Kosnik]

Hi David. This looks ok. I've checked it in.

The only thing I'm curious about is the LIBS bit: do you need to reset LIBS
after all these checks are done, ie

> +       AC_CHECK_LIB(iconv, iconv, libiconv="-liconv")
> +       ac_save_LIBS="$LIBS"
> +       LIBS="$LIBS $libiconv"
> + 
>         AC_CHECK_FUNCS(iconv_open iconv_close iconv nl_langinfo, \
>         ac_XPG2funcs=yes, ac_XPG2funcs=no)

         LIBS=$ac_save_LIBS

?
