I suddenly realise it is not obvious why I left a space in there.

That's on purpose, otherwise ./configure gets awfully confused, and
does not even try to find PAM headers and simply bails out before even
doing anything to detect PAM.

I can re-spin with a better commit log (and/or a comment in the patch)
if needed. Or it can be added by the committer. ;-)

Regards,
Yann E. MORIN.
