Subject: [PATCH][c89] wrong usage of compiler constants
From: Sylvain BERTRAND <sylvain.bertrand@...eek.net>
Using a c89 compiler fails due some wrong usage of compiler constants.
Trivial and harmless fixes.
Signed-off-by: Sylvain BERTRAND <sylvain.bertrand@...eek.net>

work based on mainline 9c87c9f41245baa3fc4716cf39141439cf405b01:
(will enable an IP/USB-ethernet kernel to be compilable and runnable)
