Subject: [PATCH] Make: handle warning files while building in a directory
|
|
|
|
The dependency on the warning files breaks when we are building in a
|
|
directory *and* the files already exist from being shipped with the
|
|
distribution tarballs. The make VPATH simply isn't sophisticated
|
|
enough to deal with it, so let the C compiler handle it by #including
|
|
the generated file from a dummy C file.
|
