Compiling GNU Chess with DJGPP: where is autoconf ???

[Ihor . Bobak]

 Dear All,

I am trying to compile GNU Chess with the help of DJGPP.
I am doing everything exactly as in the instruction:
----------------------
First, cd to the src directory.

Run autoconf to build configure from configure.in

Then run configure to build Makefile from Makefile.in.

Now run "make" to build gnuchess.exe
----------------------

Can anyone tell me where to get autoconf.exe and configure.exe ?
I don't have them after installation of DJGPP :-(

Can anyone give a link where I can download all necessary packages?

Thank you very much in advance.

Best regards,
 Ihor.
