Yeah, but maybe there is something to be investigated to avoid fork
when running recipies... I've read somewhere that spawn was much more
performant than fork under cywin (note: I don;t know if make already
do that or not, nor what are the implication...)

Another thing: I think most of these mkdir could be avoided at the
cost of another layer of dependencies: create rules for every target
so that the parent directory is a pre-req target and have rules for
directories to build them... that should put most of the the workload
on make itself an limit drastically the number of mkdir...
