- Subject: [COMMIT] Remove some header usability warnings from configure
The new autoconf spits out some annoying warnings on *BSD. This fixes
them. There might be some fallout from this, but the only way to find
out is probably by committing this anyway. GNU/Linux systems should
be OK, since glibc has the policy that its header files should have no
prerequisites.

* configure.ac: Provide prerequisite headers when checking
<link.h>, <sys/proc.h> and <sys/user.h>.
* configure: Regenerate.
