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',
