ask about bison-3.0.5

[马俊]

Dear scientist,
   Here is a problem when I installed bison-3.0.5(./configure 
--prefix=/home/shenhf/majun/setup/bison-3.0.5 make&make check &make install)
When I excute make check, it shows:


493: Predicates                                      ok
## ------------- ##
## Test results. ##
## ------------- ##

ERROR: 486 tests were run,
4 failed unexpectedly.
7 tests were skipped.
## -------------------------- ##
## testsuite.log was created. ##
## -------------------------- ##

Please send `tests/testsuite.log' and all information you think might help:

   To: <address@hidden>
   Subject: [GNU Bison 3.0.5] testsuite: 440 441 442 443 failed
You may investigate any problem if you feel able to do so, in which
case the test suite provides a good starting point.  Its output may
be found below `tests/testsuite.dir'.

The system is centos6 and complier is gcc-8.3.0, any help or suggestion is 
highly appreciated. The tests/testsuite.log is attached below.
