On OpenBSD 4.4, <sys/uio.h> is not self-contained:
$ cat foo.c
#include <sys/uio.h>
struct iovec x;
$ gcc -c foo.c
In file included from foo.c:1:
/usr/include/sys/uio.h:40: error: syntax error before "size_t"
In file included from foo.c:1:
/usr/include/sys/uio.h:75: error: syntax error before "preadv"
/usr/include/sys/uio.h:75: error: syntax error before "off_t"
/usr/include/sys/uio.h:76: error: syntax error before "pwritev"
/usr/include/sys/uio.h:76: error: syntax error before "off_t"
/usr/include/sys/uio.h:78: error: syntax error before "readv"
/usr/include/sys/uio.h:79: error: syntax error before "writev"
This patch works around it:
2011-04-30 Bruno Haible <address@hidden>
sys_uio: Make <sys/uio.h> self-contained.
* lib/sys_uio.in.h: Include <sys/types.h> before <sys/uio.h>.
* doc/posix-headers/sys_uio.texi: Mention the OpenBSD problem.
