Bug#527705: kobodeluxe failing to build in Debian: enemies.h:75: error: 'const enemy_kind pipe2' redeclared as different kind of symbol

[Damyan Ivanov]

Hello David,

Below is a bugreport I got about the Debian package of kobodeluxe. As 
far as I can tell (with my limitted C++ knowledge), the pipe2 symbol 
declaration in enemies.h collides with the one in unistd.h.

This was built OK before, but since then Debian has new GCC and libc 
so I suspect they may have become more strict (or buggy?).

The patch attached seems to work around the problem by renaming pipe2 
to pipe2_kbdl, but I guess usage of namespaces or something like that 
should be the proper fix. Or, I may be completely off-track.


The bug log is available at http://bugs.debian.org/527705
It would e nice if you keep 527705 at bugs.debian.org in Cc.

Thanks for looking into this.

    Damyan
