As said by Alexandre, this is incorrect, underquoted.  But even quoted
2.13 fails.  Yep, that's a bug in 2.13, which was vastly mixing
overquotation, and underquotation.  CVS Autoconf is fixed.

*** Zen does not function properly without dlopen, sorry.])])])
/tmp % ./configure                                               nostromo 15:26
