Bug#740153: gcc-4.9: FTBFS on hurd-i386

[Svante Signell <svante.signell@gmail.com>]

Source: gcc-4.9
Version: 4.9-20140218-1
Severity: important
Tags: patch experimental upstream
User: debian-hurd@lists.debian.org
Usertags: hurd

Hi,

Currently gcc-4.9 fails to build on GNU/Hurd due to WCONTINUED not
being defined. The attached patch solves this problem by only using
that option as third argument to waitpid when available. This flag is
Linux-specific, and according to the Linux waitpid man page it was
introduced in 2.6.10.

Thanks!
