This patch does not make sense because $(srcdir)/defaults.h will always exist.
I build all the time with different object directories and I know of
many people who build with a read only source directory; explicitly so
they can test that way.
You are going to have to expand on why you need defaults.h from the
build directory and not the source directory?
As far as I Know there is no defaults.h in the build directory even.
Do you have another patch which changes that?
