I saw the bug report.  I find autotools sufficiently flexible that they
are neigh on opaque.  I *think* you'll need:

  AC_ARG_WITH([sysroot],
    [the system include directory -- default: /usr/include],
    [ AC_DEFINE_UNQUOTED([SYSTEM_INC_DIR], "$withval",
          [system include directory])

      [if test -d "$withval" ; then SYSTEM_INC_DIR=$withval
       else AC_MSG_ERROR([provided value is not a directory: $withval]) ; fi]],

    [SYSTEM_INC_DIR=/usr/include])

and then replace the INPUTLIST definition with:

  test $# -eq 0 && INPUTLIST="@SYSTEM_INC_DIR@" || INPUTLIST="$*"

using "$@" is confusing and won't actually work:

$ set a b c\ d;echo $#;f="$@";set -- $f; echo $#
3
4

Anyway, I *think* that works, but like I said, it's pretty opaque to me.
