Bug#897335: libc0.1-dev: Dev package exposes extattr_set_fd, extattr_get_fd, etc. system calls

[Hilmar Preuße <hille42@web.de>]

Package: libc0.1-dev
Version: 2.27-3
Severity: normal

Dear Maintainer,

I hope this is the right package to report on.

I noticed that proftp v1.3.6 FTBFS on kfreebsd. James Clarke told me in
bug #897168 that libc0.1-dev exposes some system calls in header files,
which are not implement in any lib, hence the link stage fails.

My impression is that functions, which do not exist should not be visible
in any header files. Consider to fix the header files.

Thanks!

Hilmar
