/usr/include/term.h breaks builds

[yobson]

Hello!

I'm currently bringing GHC up for omni os, but it will not compile due to issues with term.h

Take the following c program:

#include <term.h>
#include <stdio.h>

int main() {
	return 0;
}

We run gcc test.c

Expected Result

We get a rather boring a.out file

What happens:

      |                                )

I'm guessing that this isn't expected behaviour because GHC hits the exact same error!

All the best

Hi, the program works if you also include <curses.h> before <term.h> so a similar patch to GHC might work.

% cat c.c
#include <curses.h>
#include <term.h>
#include <stdio.h>

int main() {
        return 0;
}

% gcc c.c

I don't know whether term.h should automatically be including that, maybe somebody else has an idea.

Thanks! I'll look and see if I can work out what's going on with ghc then!
