Sorry for asking the obvious: you do have Autoconf installed, right?

If you do, the next things I'd suggest to look into are:

  - Is m4.exe a DJGPP port?  If not, perhaps Autoconf invokes it in a way 
    that fails due to compatibility problems (such as long command lines).
    Or maybe the m4 you have is not version 1.4 or later (type 
    "m4 --version" and see what it says).

  - Do you have Perl and Bash installed?  IIRC, Autoconf is a Perl 
    script, so it requires Perl and Bash.

  - Finally, find out what code fragment in Autoconf prints the above 
    error message and try to figure out why could it fail.  If you cannot 
    figure that out, post the failing fragment here and someone will help 
    you out.
