[Nico, 2009/09/07 18:32:15]

Since this is a python dict, this 'conditions' (silently) overwrites the other
entry for 'conditions' above, which means the 'chromeos==1' above won't be
evaluated and hence _chromeos\.cc$ above won't cause sys_info_chromeos.cc won't
be added on chromeos, which causes the linker failures that broke the build.

Mark, is there any way gyp could warn (or error) when a dict key is present
multiple times?
