This got out of my mind. Thanks for the pointer.

A build system that produces an output that varies depending on the order of its computations should be fixed. Otherwise, it sounds like a great source of heisenbugs and other pains. -- Lunar .''`. lu...@debian.org : :Ⓐ : # apt-get install anarchism `. `'` `-
