[PATCH] compat-util: add _DEFAULT_SOURCE define

[PATCH] compat-util: add _DEFAULT_SOURCE define

[Sergey Senozhatsky]

glibc has deprecated the use of _BSD_SOURCE define

  warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"

To make it easier to maintain a cross platform source code, that
warning can be suppressed by _DEFAULT_SOURCE.

Define both _BSD_SOURCE, _DEFAULT_SOURCE and cleanup the build.

I can see you defined DEFAULT_SOURCE, but where did you do "cleanup
the build"?  Or did you mean "define both (in order) to clean up"?

Just making sure we are not only seeing a patch half eaten by mail
transport somewhere.

yes. sorry, I meant "in order to clean up". otherwise, the build is
a bit noisy:
