Re: Expand % in wildcard function

[Mike Gibson]

Hey, I wrote just because I'm nice enough to write some code for doesn't mean 
I'm nice enough to debug it. ;)

Actually, I am.

add a backslash to the end of this line.  The newline isn't properly being 
escaped.

$(patsubst $(DOCS)/%,%, $(wildcard $(DOCS)/*)),

NOTE:  I still haven't tested it.  Perhaps if you paid me one million dollars.

P.S.  I hate spam too, but your little challenge-response thing doesn't work 
and thus makes me not want to waste my time replying.
