I just used the script

<quote>
#! /bin/sh -f
files=`find . -name "*.c"`

for _file  in $files; do
  _newfile=`echo ${_file} | sed -e "s/\.c$/_new.c/"`
  _outfile=`echo ${_file} | sed -e "s/\.c$/.oct/"`
  echo "Build $_file"
  cat $_file | sed -e 's/#include <matrix.h>//' > $_newfile
  mkoctfile -o $_outfile --mex $_newfile
  rm $_newfile
done
rm *.o
</quote>

in the cml/source directory of th latest version and built sucessfully
all of the mex files with 2.9.10 (or at least close enough to 2.9.10
that it makes no differemce)
