This patch will move _GNU_SOURCE and _FILE_OFFSET_BITS=64 from various source files to Makefile.

That's fine by me, but let's see what Neil has to say about this.

While cleaning up the #defines, we might want to get rid of a couple of unused ones at the same time. BLKPG_ADD_PARTITION, START_MD, REGISTER_DEV, MD_FEATURE_ALL, STDC, OF seem to be good candidates for removal.

There are also quite some unused defines in super-ddf.c and super-intel.c, presumably because these files contain code that was copied from somewhere else. I'm not sure if it is worth to kill these as well though.

Thanks
Andre

Why?

The reason is to clean up the code. The new files will appear soon and I want this two definitions to be set globally instead of per source file.

There's the plan to use GNU autotools to simply the build process, too.

Thanks,
Artur

Personally, I prefer them to be set just where they are needed. You could possibly convince me to put them in mdadm.h, but not in Makefile.

That plan should be dropped immediately. It won't happen.
