Perfect solution for a lazy programmer... ;-) More seriously: Perhaps I was a 
bit unclear, I don't propose to use an autoconf test for each and every tiny 
detail. Using feature-based #ifdefs and #defining them manually in a single 
well-known place based on the platform is often enough. Avoiding the annoying 
"What the hell does this #ifdef really test??"-questions is the point here...

Cheers,
