That's possible indeed. There are discussions whether to support all
compilers deps file formats inside Ninja or in another program (see
the deplist branch and discussion thread). The deplist branch is an
attempt to provide a common format to store the dependencies in a
fast-to-parse format.

Currently, it is not merged yet and Ninja still relies on its own
parser which is probably not bug free and does not have all the
work-around required for all compilers versions.
