We should return an error here, but I have no idea on how to do this.
main/gridinit.c
Outdated

Do we want to allow hexadecimal signals and things like that?

I don’t think we should put this thing here. It’s not good for code readability.
It would probably be best to create a plateform file or a signal file for this.

It’s a funny thing that travis do not know But I guess travis uses some old linux. |

First, lot of copy and paste, you should use a macro
#define ITEM(x) {x, #x}
and have
] SIGNAL [] = {
ITEM(SIGABRT),
ITEM(SIGHUP),
...
}

IMO we should emit a message with kill return an error
