Hello,
Trying to check other OSS's after installing bison-3.3,
and found flex-2.6.4's make ckech failes.
This is not occur with bison-3.2.4.
I can not distinguish which has the problem.
$ uname -a
SunOS xxx 5.11 11.3 i86pc i386 i86pc
$ gcc --version
gcc (GCC) 7.4.0
Error in flex-2.6.4 is as follows.
