Hello,
on a second thought, I think I was completely wrong here:

Autoconf sources, configure and config.status contain whitespace
which has to be preserved. (The [<tab><space>]* regular expressions
in config header sed scripts are an example.)
The confdefs.h initialization is not special.
Thus I believe there is no problem with the patch below.
OK to commit?
