Bug#439859: /usr/include/sys/sysmacros.h defines "major", "minor" and "makedev" as macros

[Simon Richter <sjr@debian.org>]

Package: libc6-dev
Version: 2.6.1-1+b1
Severity: normal

Hi,

these names are defined as macros, making software that uses one of them
as an identifier miscompile (if the definition is seen everywhere, the
list of exported symbols changes in an incompatible way) or break (if
the definition is not seen everywhere, for example because only the
implementation of a function needs them).

It is specifically a problem with orbit2cpp; CORBA::Exception has member
functions "major" and "minor" describing the exception; with these
definitions in effect, compilation of functions accessing these fails
with

error: `class CORBA::SystemException' has no member named
`gnu_dev_minor'

This can be worked around to some extent by undefining the macros,
however that breaks if some implementation of an interface needs them.
