'make check' fails

[Andreas Steenpass <steenpass at mathematik dot uni-kl dot de>]

I check out the Cygwin sources from the CVS and left everything
unchanged. Then I followed the instructions on how to build Cygwin which
I found here:

http://cygwin.com/faq/faq.programming.html#faq.programming.building-cygwin

Everything went through smoothly including make install. But now, when I
run 'make check' in build/i686-pc-cygwin/winsup, I get the following:

steenpas@zoppo:~/Cygwin/build/i686-pc-cygwin/winsup$ make check

(Sorry for the German snippets.) In a secong attempt, I deleted
build/i686-pc-cygwin/winsup/config.cache before the 'make check'. Then
configure succeeded, but I still get the same error, only the line

config.status: error: cannot find input file: `config.h.in'

is missing. Does anybody have an idea how to fix this and to run the tests?

Regards,
Andreas
