Bug#442427: Changes to sysmacros.h cause FTBFS in previously good software

[Ari Pollak <ari@debian.org>]

Package: libc6-dev
Version: 2.6.1-4
Severity: grave

After the changes in -3 to sysmacros.h to fix #439859, software that
defined a major or minor variable now breaks, whereas it used to compile
fine. I have not heard a valid rationale for breaking things resulting
from that patch. gimp currently fails to build with the following:
