>Description:
Autodetection of <sys/rtprio.h> presence fails due to missing typedefs
provided by <sys/types.h>. And rtprio(2) manpage mentions both.
>From docs/ChangeLog:
1.1.6 (19981019):
- Option for realtime priority in FreeBSD added by Douglas
Carmichael <dcarmich@mcs.com>
Apparently, autoconf-2.12 (in xmp-1.1.6) only checks headers with CPP but
autoconf-2.67 (in xmp-3.4.1) also tries to compile them with CC and fails.
