control: reassign -1 src:virtualbox control: forwarded -1 https://www.virtualbox.org/ticket/16052
>Not sure if this would be the xserver's fault for not defining _XOPEN_SOURCE or >__need_sigset_t, or virtualbox. I'm thinking the latter as in a simple test >case, including signal.h without doing anything else gives me sigset_t. thanks, lets ask vbox developers about their opinion, in any case we have to fix the build in a later step. (since security team asked to remove it from Stretch... this might be a good reason) G.
