I'm working up a patch for libresolv but I'm having one problem. In
newlib/libresolv/configure.in I have:

  [...]
  NEWLIB_CONFIGURE(..)
  [...]

(I used libm as a template) Which gives me an error when making
`all-newlib-target':

  running /bin/sh /local/cvs-mirror/winsup/newlib/libresolv/configure
  [...]
  /local/cvs-mirror/winsup/newlib/libresolv/configure: line 1485: syntax error near unexpected token `..'
  /local/cvs-mirror/winsup/newlib/libresolv/configure: line 1485: `NEWLIB_CONFIGURE(..)'
  configure: error: /local/cvs-mirror/winsup/newlib/libresolv/configure failed for libresolv

  /local/cvs-mirror/winsup/newlib/libresolv/configure: 715: Syntax error: word unexpected (expecting ")")
  configure: error: /local/cvs-mirror/winsup/newlib/libresolv/configure failed for libresolv
  make: *** [configure-target-newlib] Error 1

I'm guessing this is an Autotools cockpit error on my part. I'm using
autoconf-2.57 and automake-1.7.5 (Cygwin), if that helps. Any clues on what I've
done wrong? I re-autotooled using `aclocal -I NEWLIB-SRC-DIR; autoconf;
automake' (where NEWLIB-SRC-DIR is the top-level newlib dir; so it can pick up
the .m4 files) in the libresolv directory.
