  manywarnings: update the list of "all" warnings
  
  * m4/manywarnings.m4: Unite lists, and add many new options.
  * build-aux/gcc-warning: New file.
  
  Run this command with the latest gcc to see if they have added
  options not yet on our list:
  
  gl=.; comm -1 -3 \
    <(sed -n 's/^  *\(-[^ ]*\) .*/\1/p' $gl/m4/manywarnings.m4 |sort) \
    <(gcc --help=warnings|sed -n 's/^  \(-[^ ]*\) .*/\1/p' |sort \
      |grep -v --line-regexp -f <(cut -f1 $gl/build-aux/gcc-warning.spec))
