You are probably not setting the M4 environment variable correctly. The
instructions state:

    To run this version of flex, you will need to set the M4 environment variable
    to point to your installation of m4. You need one of these in order to run
    both bison and flex, and it sometimes comes packaged with bison.

    If you are using this in a buildfarm member, you can set that environment
    variable in its config file, in the build_env stanza, something like:

    	M4 => 'c:\path\to\bin\m4.exe',
