Some of headers are not self containing

[kaliber]

Use following program to show defects:

#!/bin/sh

DIR="/boot/develop/headers/posix/"
for i in `find $DIR -name '*.h'`
do
	f=${i#$DIR}
	cat > test.c << EOF
#include <$f>
int main() { return 0; };
EOF
	echo "Testing $f"
	gcc test.c
done

Figured I'd run the test and post the results here.

I then inserted an #include <sys/types.h> right before the #include <$f> and then reran the test and here's what I got:

So it would seem that m68k/arch_setjmp.h, netinet/ip_icmp.h, netinet/ip_var.h, resolv.h may need fixes, or they also have a required include missing. In the regex.h file it states that <sys/types.h> is required first.

[kaliber]

I've created a complete patch. I skip regex.h fix due to the comment: /* POSIX says that <sys/types.h> must be included (by the caller) before

<regex.h>. */

[axeld]

Patch applied in hrev26841. I guess this is only a part of this ticket?

[kaliber]

In my opinion the patch is a complete. To be sure check it using simple script included in the first comment.

I left resolv.h as is, and the rest looks fine, thanks!
