The previously used AC_SEARCH_LIBS uses AC_LANG_CALL, which is discouraged because it intentionally violates the C type system: it has no way of specifying function parameters, so it does not include the required headers to suppress type warnings: https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Generating-Sources.html The new code does what AC_SEARCH_LIBS does, but uses AC_LANG_PROGRAM instead of AC_LANG_CALL. It explicitly includes iconv.h and calls iconv_open with the correct number and type of arguments. This fixes compilation on systems where libiconv’s iconv.h is discovered first, but glibc also provides iconv. Previously, this would result in configure discovering glibc’s iconv, and make failing to compile because -liconv wasn’t specified, but iconv.h pulled in libiconv.
