Re: A small simplification

[Stepan Kasal]

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?
