    Hi Paul :)

    I supposed that some caching was the cause, but for me was
reasonable that $wildcard will not expand if the new file wasn't

    In the real makefile, it is an implicit target. I will see if I
can make explicit targets, because now all affected files are
implicit ones (well, they match something as path/* and the like).
Otherwise I'll stick to the $(shell) solution.

    Interesting ;))))

    Thanks a lot for your answer and explanation. Now I have things
clearer, Paul :))

    Note that this is a generated Makefile, part of a bigger proyect
not yet released, but since it is GPL and it may be dumber than I
think, I attach it so you can see what is all about. Feel free to
ignore and feel free to criticize it ;)) Currently you cannot do
'make install' without doing before 'make all' due to the $(wildcard)
function issue, but I'll fix ASAP ;))
