Strange. On this system I would have expected that configure finds
  HAVE_FNMATCH_H = 1
  HAVE_FNMATCH = 1
  REPLACE_FNMATCH = 1
but it seems that it found
  HAVE_FNMATCH_H = 1
  HAVE_FNMATCH = 0
  REPLACE_FNMATCH = 0

Can you confirm this hypothesis? The config.status contains the
values of these variables.

Can you find out why? The config.log contains the execution log of
the autoconf test. Look for "checking for fnmatch...".

Also, did you "make distclean" before reconfiguring with the files
from the updated gnulib?
