Emacs build failure

[Kai Großjohann]

I always use the same script to build Emacs.  The script starts with
"make distclean", then invokes autoconf, configure, and make.

The compilation aborts with the following error:

I have seen a similar problem before; can you teach me how to solve
problems like these myself?  Then I can actually do something useful
rather than having to keep bothering you with this.

Thanks,
