Re: gnustep-make now supports building in separate build directory

[Dan Hitt]

Hi Nicola,

Thanks very much for implementing this feature (and all your other
contributions).

As you point out it is useful if you have read-only sources, and
it is also useful if you're trying to debug some building problem
(you can build multiple times with differen environments,
compilers, etc etc and compare the results).
