sysroot configury broken?

Hi all,

I see this in configure.ac:

AC_ARG_WITH(sysroot,
  AS_HELP_STRING([–with-default-sysroot],
    [Add --sysroot=<path> to all compiler invocations.]),
    withval="")
AC_DEFINE_UNQUOTED(DEFAULT_SYSROOT,"$withval",
                   [Default <path> to all compiler invocations for
–sysroot=<path>.])

The macro seems to suggest that I should write "--with-sysroot", while
the help string is pushing me towards "--with-default-sysroot". Which
is the official (intended) one?

Can somebody fix this confusion and regenerate please?

Cheers,

    Gabor
