Can you look in config.log and find why the tests fail to find the
system versions of fnmatch and glob?

What is the output from

  nm liboctave/glob-match.o | grep fnmatch

?  I expect that the version of fnmatch that it is expecting will have
a mangled name.

Also, can you determine precisely which fnmatch.h file is being
included?  Does it include lines like

  #ifdef        __cplusplus
  extern "C" {

  #ifdef        __cplusplus

around the contents of the file?  If not, does changing the line

  #include <fnmatch.h>

in liboctave/glob-match.h to be

  extern "C" {
  #include <fnmatch.h>
