+Subject: [PATCH] iconv: tweak iconv detection
+
+Tweak PHP_SETUP_ICONV from aclocal/acinclude.m4 to not
+PHP_ADD_INCLUDE $ICONV_DIR/include since the tests use
+test instead of AC_TRY_LINK to find headers which is bad,
+specially when adding /usr and /usr/local to the mix.
+Do basically the same with ext/iconv/config.m4 by tweaking
+PHP_ICONV_H_PATH which, again, uses test and absolute paths.
+
+Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar>
+[Gustavo: convert to nice m4 instead of patching configure]
+[Gustavo: update for 5.6.10]
