Re: patsubst: Whitespaces are not replaced by spaces | Possible issue in make or the documentation

Hi Marek!  Please choose just onee mailing list to ask your question,
rather than sending it to multiple lists.  Either one would be
appropriate for this question IMO.

I believe that was trying to discuss whitespace etc. within the pattern
words, not within the to-be-substituted text.  But, it doesn't even
work there.

I think you should ignore that paragraph in the documentation and
pretend it's not there.  I have no idea what it really refers to.


If you do want to strip out whitespace etc., you should use the $(strip
...) GNU Make function.
