This error seemed to be header file location problem.
glob.o fnmatch.o were complied with header files, glob.h and fnmatch.h in 
libgnu/lib, respectively.
However, it seem that glob.h and fnmatch.h in libgnu/lib did not to be used in 
the compiling
glob-match.cc.  I placed the different version of  glob.h and fnmatch.h in the 
path specified in
CPPFLAGS.  The the different version of  glob.h and fnmatch.h are used for 
building 3.2.x branch.

Was the behavior correct ?

Anyway, I replaced the glob.h and fnmatch.h by those in libgnu/lib.
This time I have met compiling problem

Any suggestions ?
