Dear Rhys,

Thanks a lot for your fast reply. 

That is a bit disappointing, though: it generates a lot of extra work for the author, only to find out what autoconf already knows: where it 
could find a particular header file. It will also make the scripts less 

Am I overlooking something? Is there a technical reason why that information 
cannot be.communicated to the user? If not, I suppose I could file a feature 

Thanks again, Jan.
