Thx alot!

I know that my path is messy, but having "/" in the path should not be 
all too fatal.

Furthermore, I probably did not set any of those strange paths myself 
(this is afterall Windows ;) ).

@Eliot: Good idea to set MANPATH!

 >MANPATH=/usr/share/man PATH="/usr/bin:/foo" strace man bar |grep 
'foo/share'

returns nothing and fixes the issue!

IMHO at least in Windows/Cygwin creating MANPATH from PATH makes no 
sense! (although I now get the idea what was the rationell!) Reasonably 
setting MANPATH should IMHO be a default...
