Bug#522774: libc6-dev: uses “__unused” as identifier, which is traditionally used by BSD as macro

[Thorsten Glaser <tg@mirbsd.de>]

Package: libc6-dev
Version: 2.9-6
Severity: wishlist

(mass filing with linux-libc-dev and libc6-dev)

/usr/include/aio.h:  char __unused[32];
/usr/include/aio.h:  char __unused[32];
/usr/include/bits/stat.h:    long int __unused[3];
/usr/include/bits/stat.h:    long int __unused[3];
/usr/include/bits/utmp.h:  char __unused[20];           /* Reserved for future use.  */
/usr/include/bits/utmpx.h:  char __unused[20];          /* Reserved for future use.  */
/usr/include/netdb.h:  int __unused[5];
/usr/include/netinet/ip_icmp.h:      u_int16_t  __unused;

These conflict with the traditional use of __unused by the BSDs, which
predates use of __unused as identifier by Linux and glibc headers.

For example, the Debian package libbsd-dev includes the following code:

#ifndef __unused
# ifdef __GNUC__
#  define __unused __attribute__((unused))
# else
#  define __unused
# endif
#endif

It however was ifdef’d out due to this problem. A personal package of
mine, mirmake, fails to build on more recent Debian systems because it
does _not_ ifdef it out, since otherwise, some BSD software cannot be
compiled (without extra patches).

Please file this bug with your respective upstreams *and* patch the
header files in question yourselves, to bridge over the response time
waiting for upstream to fix it.

Thanks!
