It is really old, and if you have installed all the GNU tools
(fileutils, shellutils, ...) you don't need it.

The "official" name for the DJGPP is i[3456]86-pc-msdosdjgpp
and is recognised by configure already!! So do not use the
--host switch, but the following patch

and then run autoconf to get a updated configure script.

That's now really a bad idea. running

make CFLAGS=-O2

does the same.

Apply the following patch and it should work (of course before running
the configure script!!)

And last but not least, you will need some special tricks before
running the configure script and also before running make. So I made
two scripts, which are replacements of the configure script and the
make command:

And a last note: Please use the above at your own risk, but it worked
at least for me.

Your problem is probably, that you haven't compiled so often a GNU
package so you don't know, where to search and fix such common problems.
