Well, currently my hack to configure.in replaces iconv with giconv and
iconv_open with libiconv_open so that you have:

AC_CHECK_LIB(giconv, libiconv_open, , [
	AC_CHECK_FUNC(libiconv_open, , [
		AC_MSG_ERROR([*** You need giconv for libmutt.])
		])
	])

Note that I have to pass gcc the paths to the header and the library
explicitly by setting (in the environment)
CPPFLAGS="-I${LOCALBASE}/include" and LIBS=-L${LOCALBASE}/lib -lgiconv"
where LOCALBASE is set by my build environment (by default) to/usr/local. 
If this isn't done, the test will fail.
