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.
Youneed 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_envstanza, something like:
M4 => 'c:\path\to\bin\m4.exe',
