Updating autoconf did the trick to replicate this behaviour.
However, to me it looks like the problem is in autoconf indeed, so i'm
cloning and reassigning. If support of getmntent is found, HAVE_GETMNTENT
is defined empty instead of to 1, although the documentation states differently.
This change seems to have introduced the bug:

http://cvs.savannah.gnu.org/viewcvs/autoconf/autoconf/lib/autoconf/functions.m4?r1=1.108&r2=1.109

I'll include a workaround for this autoconf bug in the next upload.
