[bug] pkg-config-0.21's AM_INIT_AUTOMAKE out of sequence in configure.in

[snowcrash+pkg-config]

i'm building pkg-config-0.21 on osx 10.4.8, with,

  gcc --version
    powerpc-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc.
build 5367)
  autoconf --version
    autoconf (GNU Autoconf) 2.61
  automake --version
    glibtool --automake (GNU automake) 1.10
  glibtool --version
    ltmain.sh (GNU libtool) 1.5.22 (1.1220.2.365 2005/12/18 22:14:06)

after,

  glibtoolize --force --copy

then,

  autoreconf -f -i

fails at,

...
	configure.in:106: AC_CONFIG_AUX_DIR must be called before AM_INIT_AUTOMAKE...
	configure.in:4: ... AM_INIT_AUTOMAKE called here
	autoreconf: automake failed with exit status: 1

changing/moving in,

  vi configure.in
  ---------------------
    @4
    -	AM_INIT_AUTOMAKE(pkg-config, 0.21)

    @110
    +	AM_INIT_AUTOMAKE(pkg-config, 0.21)
    	AC_FUNC_ALLOCA
  ---------------------

now,

  autoreconf -f -i

completes ok, although a bit 'noisy',

then,

  configure
  make
  make install
