   Actually I think the 'cheesy gate' in MkDir should be enough since 
bjam should always pass some sort of unique standardized paths to it. I 
believe the problem is that Boost Jam tracks the same target multiple 
times in case it gets specified using different paths.

   In an ideal world, Boost Jam should realize that there are several 
different requests for the same folder to be created and create that 
folder only once. In case that folder already exists then the action 
should not be triggered at all.

   We dealt with a similar issue on Windows recently where it was doing 
the exact same thing with short and long Windows path names.

   I'll try to find time to look into this but can not promise anything 
for a while longer... I'm currently swamped in work and already sleep 
deprived... :-)
